Release that Witch

Westland, Bianbu Town.

The washing stone purchased from Silver City was full of four boats, and it took several days to unload it.

Now that there is enough raw material, the soap production plan should be officially put on the agenda.

The matching workshops and warehouses have already been set up. The soap factory is located next to the industrial park, next to the No. 2 steam assembly plant, and the shape is exactly the same. The roof, beams and wall panels are made of wood, the size is smaller, and the wood cutting and lifting work is carried out by the witches, so the construction period takes only one week.

The use of washing stones, also known as trona, to make soap is essentially a series of chemical reactions. The required raw materials are also very common, in addition to soda ash, a large amount of lime milk and grease are required. The lime milk is a suspension which is precipitated at the bottom of the container after immersing the lime in water, and is used for reacting with soda ash to form caustic soda, and then reacting with caustic soda to form higher fatty acid salt and glycerin. The former is even soap, while the latter is an extremely important raw material for explosives.

When the soap was made before, Roland had already tested a full set of reaction processes in the backyard of the castle. The principle is basically the same, but to expand a small number of trial production into mass production, it is still necessary to develop reasonable processes and specifications, and more importantly, professional chemical personnel are needed to guide production.

To this end, he called the chief alchemist into the office.

"His Highness, you have requested a large-scale process for the production of sulfuric acid. I have already thought of a possible solution." As soon as he entered the door, Camo Spoel yelled, "But this requires a lot of lead and makes lead." The blacksmith of the container, I heard that some of your witches can cut the metal accurately. The sizzling shovel is what she got, can I..."

"Of course, report the shape and size of the container you requested, I will let the Witch Alliance do it," Roland waved to him to sit down. "I am looking for you today not for acid, but for another task. ""

"His Royal Highness, I really can't spare time to do anything else," Kaimo shook his head. "The large-scale acid production is a formidable challenge. I have to go all out." He paused and added. "The disciples don't do either. They are helping me prepare for this. One can't leave."

"Reassured, you can't use too much time," Roland drank his mouth. "You don't need to adjust your proud disciples to take charge. Just a few apprentices."

"That... what is the mission?"

“The soap is a cheap version of the soap in the convenience market. It has the same function as the soap except for the taste. It can be used for bathing, washing clothes, and cleansing dishes.”

“Is the saponification reaction mentioned in Elementary Chemistry?” Kaymo touched his beard. “The one that reacts with sodium hydroxide and oil to form alcohol and salt?”

I have to say that it is a very strange feeling to hear the standard chemical noun from an alchemist. This word is actually created by myself. Roland resisted the smile, and the first point was right. "Yes, it is the saponification reaction recorded in the ancient book. I also used it to find out how to make soap."

"So what do you need me to do? If it is not very important, I suggest that you go to production later. After all, your people will have no problem even if they don't take a bath for several days. Clothes and plates are soaked directly in the river. It’s just fine.”

“It’s very important,” the prince stressed. “Or, it’s not important to make soap, but the by-products of the production process are what I’m in urgent need of now.”

"You mean... alcohol?" Kemer didn't think so.

“Yes, it’s alcohol, you can call it glycerin,” Roland said. “It’s an extremely important raw material, and it’s no less important than two acids.”

"Well," Camo Spoel shrugged. "But I said, I don't have time to implement it myself."

He vomited gasfully and dealt with the chief alchemist. It was really a tiring thing. "You just pick a few clever apprentices and demonstrate it in front of them. I will recruit some people to produce, but they After all, there is no way to know about chemistry, so someone has to check all the links.” The prince paused a little. “You can also think of it as a chemical experiment that has never been practiced. If it is placed in an alchemy workshop, this process can mean several alchemists. The discovery of the formula is enough for an apprentice to be awarded the title of alchemist."

Probably the last sentence convinced Kemer. "If that's the case, I will take an afternoon to teach your content to the apprentice."

“Very good,” Roland smiled. “You should also know that the most important thing in the production process is to make enough sodium hydroxide,” he wrote the reaction formula on paper. Before the synthetic alkali process was invented, the trona was The most important alkali-making raw material, the latter is mainly composed of sodium bicarbonate, which can be decomposed into sodium carbonate, carbon dioxide and water by heating. Because of the rich raw materials and simple process, it is still used until modern times. “When the washing stone is heated and decomposed, dissolved in water, and filtered, a pure sodium carbonate solution can be obtained.”

"The next step is to use it to heat the lime milk to get a sodium hydroxide solution. You should think of it very easily," he explained as he wrote, "clarify, distill, mix, and repeat this step until the solution concentration. It is possible to precipitate a large amount of crystals after cooling."

These are all related to the "Elementary Chemistry", because of the large number of two bases, it is very confusing (such as caustic soda, caustic soda, soda ash, baking soda, baking soda, soda, etc.), but also an important knowledge of the exam, he I didn’t have to recite the textbook related content at the beginning, so I still remember it clearly.

“I understand,” the chief alchemist read the reaction from start to finish. “But what about His Royal Highness, grease?”

"I will arrange for these materials to be sent to you." Animal fats are still expensive in this era, but the last time the seed purchase tour of the Guardian brought the olive tree seeds from the Dragon Ridge, Bianbu Town There is a reliable source of vegetable oil. Although it is currently only planted on a small scale in the backyard of the castle, there is a ripening ability of the leaves. It is not a problem to harvest a bunch of fruit a day.

The extraction of olive oil is also very simple. After the fruit is ripe, it can be oiled by physical cold pressing, and then filtered through the filter to remove debris and slag, and the clear oil can be obtained.

Finally, after a brief explanation of the requirements for the preparation of soap and the retention of glycerin, Roland let Camo Stern leave the office.

As a result, when the soap factory started, he had a stable access to glycerin.

With glycerin, it means that the real smokeless emission medicine and the powerful explosives are not far from him. (To be continued. Your support is my biggest motivation.)
