The next morning, Xu Qiang and He Yonghong went to Changzhou and signed a contract for the research and development of a new perfume.

Since the successful cooperation on the last feed project, the officials of the Changzhou government obviously had a better attitude towards Xu Qiang. That night, he and He Yonghong were once again warmly entertained, during which they drank a lot of wine.

After returning from Changzhou, Xu Qiang, who got the contract, immediately started developing a new perfume.

Xu Qiang has always used the laboratory of the Chemical Engineering Department of Shanghai Institute of Mechanical Engineering. The conditions in all aspects are quite good, so there is no problem at all in developing perfumes here.

Moreover, compared to when Xu Qiang was at the peat field in Jiangxi, the chemical raw materials here are quite complete. It can be said that all the raw materials used to make perfume are available. In addition, the purchase of chemical raw materials in Shanghai is also quite convenient. There are many large and small chemical plants around Shanghai, so even some scarce chemical principles can be easily purchased.

The most important step in making perfume is the production of essence, and for Xu Qiang, this is a piece of cake. When he was in the peat field, he would prepare various spices for shampoo and soap in the workshop almost every week. He was familiar with all the craftsmanship and it was not difficult for him at all.

In just three days, Xu Qiang created nine artificial synthetic fragrances with different scents, including leaf alcohol, cinnamic alcohol, pure rosin, butyl acetate, cinnamic acetate, amyl butyrate, as well as rose oxide, ambroxan and lactic acid.

With these nine spices, Xu Qiang can mix dozens of flavors. In addition to the common osmanthus, jasmine, and rose, there are also cloves, lavender, mint, lily, lily of the valley, daffodils, lemons, strawberries, etc. There are many varieties.

The requirements for the ratio of raw materials in blending perfume are quite strict. Even if the raw materials are slightly more or less, the smell of the final product will be very different. Fortunately, Xu Qiang has a strong memory, and relying on the formulas from his previous life, he can accurately grasp the key techniques.

"Come here, don't be shy!"

At this time, Xu Qiang had just finished preparing a fruit-flavored essence and greeted the girl at the door.

These days, Xu Qiang has been making perfumes in a special laboratory provided to him by the college. As the smell of various perfumes has spread to the entire corridor of the laboratory building, it attracts many students to come here to check it out almost every day. The female college students in the college seem to lack immunity to these scents and often stand at the door to watch but are too embarrassed to come in.

But after hearing Xu Qiang's call, a few girls finally couldn't help but come in.

"Hello, Teacher Xu!"

The story of Xu Qiang's development of aramid paper and his award-winning performance at the BJ had long been circulated on campus, and Xu Qiang had become a celebrity here. So even though they were of similar age, these students would still respectfully address Xu Qiang as "teacher" when they saw him.

"Do you usually use perfume?" Xu Qiang asked.

"No need..." Several girls looked at each other and then shook their heads.

"Well, I have a dozen freshly blended fragrances here, you can smell them."

As Xu Qiang spoke, he took out more than ten bottles of essences that he had prepared in the past few days from the test bench and let the students experience them.

“Is this apple flavored?”

“Mine smells like rose.”

"smell good……"

After the girls picked up the bottles and smelled them, the atmosphere suddenly became lively, and everyone's face showed uncontrollable excitement.

Female college students these days basically go out with no makeup on. Not to mention perfume, even ordinary cosmetics are rarely used.

However, they have a natural attraction to scented cosmetics, and among the best daily chemical products bought these days, almost every girl has a set of scented oils, shampoo powders, and vanishing creams.

Compared to daily necessities like vanishing cream, the smell of perfume is obviously stronger, and Xu Qiang mixed so many fragrances in one breath, which is far beyond the scents they usually come into contact with, so they are very excited.

"Teacher Xu, how did you configure all these things?"

“Yeah, it’s amazing!”

"Can you sell us a bottle? I like the scent of this bottle..." For a moment, Xu Qiang was surrounded by these girls, and they all expressed their desire to buy Xu Qiang's perfumes.

"These things are semi-finished products and cannot be used directly." Xu Qiang smiled and continued, "If you like, you can participate in my experiment. I will make some sample perfumes and you can try them out. But I need your feedback and suggestions. After the experiment is over, I will give each of you a bottle."

"Ok."

"I want the lily of the valley scent. It smells so good..."

For a moment, everyone expressed their willingness to help, and several girls held the bottles of perfume, looking like they couldn't let go.

While Xu Qiang was explaining the configuration principles of the essence to the girls, Liu Siying and He Yonghong had appeared at the door at some point.

Suddenly, there was a burst of music outside. This was the reminder for lunch in the school cafeteria. Then, the girls in the laboratory put down the bottles of perfume in their hands and left the laboratory reluctantly.

"Xiaoying, you're here." It was not until this time that Xu Qiang saw Liu Siying standing at the door, and he immediately hurried to greet her.

"It's quite lively where you work..." Liu Siying said with a smile, her beautiful eyes flashing.

"Xiao Liu, let me tell you, Xu Qiang is very familiar with the girls in the college. Every time they meet him, they call him Teacher Xu. He is even more popular than TV stars." When He Yonghong saw this scene, his lips immediately curled up and he said to Liu Siying.

"Get lost!" Xu Qiang rolled his eyes at He Yonghong and quickly said to Liu Siying, "Actually, I've been developing perfume these days. The smell is so strong that it can be smelled throughout the corridor, so these students wanted to see what it is. There's nothing else to do..."

"Yeah." Liu Siying nodded gently after hearing this, and then said: "I also smelled the fragrance when I entered your laboratory building. This fragrance feels so strong. It feels a bit like the fragrance of the shampoo that Wang Yongsheng used to sell in the factory..."

"The shampoo sold by Wang Yongsheng was actually made by Xu Qiang in the village, and the two of them made a lot of money together." He Yonghong said with a smile.

"No one will think you are mute if you don't speak!"

"I see, that's what I was thinking." Liu Siying suddenly understood what was going on, then picked up a bottle of perfume and asked Xu Qiang, "Is this the perfume you made?"

"This is essence and cannot be used directly. If you want to make it into perfume, it needs to be processed." Xu Qiang smiled and continued, "These dozen bottles are all essence samples. You can smell them. If you like any one, I will give it to you after I make it."

"That's great." Liu Siying did not refuse Xu Qiang's kindness, so she picked up the bottles and smelled them one by one.

"This bottle of clove is good... the lemon one is also good... the lavender smells really good..." In just a moment, Liu Siying was attracted by Xu Qiang's perfumes. She held the bottles like a child who had discovered treasures, and looked like she couldn't let go.

"I'll give you a bottle later. If you run out, I'll make another one for you." Xu Qiang naturally would not miss such an opportunity to please Liu Siying.

"This is amazing... How did you make it? Was it extracted from flowers?" Liu Siying asked.

"These are all synthesized from chemical raw materials, and can also be extracted from flowers, but the cost is too high. Several tons of petals can only produce a dozen grams of essence..." Xu Qiang explained.

"That's so precious." Liu Siying said in surprise.

"If I have the chance in the future, I will definitely make you a bottle of perfume made from natural flowers." Xu Qiang smiled and continued, "By the way, why did you come here to see me today?"

"A telegram was delivered to the message room just now. It was from the Fifth Ministry of Machine Building, saying that Deputy Director Meng from the General Office would be coming over, and asked you to be on standby in the dormitory in the afternoon. He may have something important to tell you... We didn't see you in the dormitory building just now, so we came here to look for you." He Yonghong said.

"Deputy Director Meng? Meng Guangming!" Xu Qiang's eyes suddenly lit up and he said, "It seems that he should come to Shanghai to establish a research institute..."

"Is the ministry really going to build a chemical engineering research institute in Shanghai?" Liu Siying said in surprise.

"This is what Minister Zhang and I agreed on last time." Xu Qiang nodded and continued, "But this also comes at a price. Developing high-energy explosives is not an easy job..." (End of this chapter)
