Release that Witch

287. Chapter 287 Preparation of Soap Factory

    Western Region, Border Town.

    The washing stones purchased from Silver Light City were filled with four boats, and it took several days to unload them.

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

    The supporting 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 witch, so the construction period takes only one week.

    The use of wash stone, also known as trona, to make soap is essentially a series of chemical reactions. The required raw materials are also very common, and in addition to soda ash, a large amount of lime milk and fat are required. The lime milk is a suspension which is deposited in 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 extremely important for explosives.

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

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

    “His Royal 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, Cam Schuire shouted. “But this requires a lot of lead, and the blacksmith who made the lead into a container. I heard that someone in your witch can cut the metal accurately. The sizzling shovel is her. I got it, can I…”

    “Of course, report the shape and size of the container you requested, I will let Witch Union 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,” Cam shook his head again and again. “The large-scale acid production is a formidable challenge. I must go all out.”He paused, adding that “the disciples are not good either, they are helping me prepare for this, and 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 responsibility. Just a few apprentices.”

    WellWhat 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 cleaning dishes.”

    “Is the saponification reaction mentioned in «Elementary Chemistry»?”Cam 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 mouth, especially the word was created by myself. Roland held back his smile and said that he was serious. “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 to go to production later. After all, your citizen has no problem even if you don’t take a bath for a few days. Clothes and plates are just like bubbles in the river. ”

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

    “You mean…AlcoholCam didn’t take it for granted.

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

    “Well,” Cam Schuire shrugged. “But it’s good, I don’t have time to implement it myself.”

    He sighed out and dealt with the chief alchemist. It was a tiring thing. “You just pick a few clever apprentices and demonstrate it in front of them.” I will recruit some citizens for production, but after all, they don’t know anything 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 you have never practiced. If you put it in an alchemical workshop, this process can mean the discovery of several alchemy formulas, enough for an apprentice to get the alchemist title.”

    Probably the last sentence convinced Cam. “If that’s the case, I will take an afternoon to teach your content to the apprentice.”

    “Very well,” Roland smiled, “You should also know that the most important production process is to make a sufficient amount of sodium hydroxide,” he wrote on the paper reaction formula-before the synthesis of alkali technology was invented, the natural alkali is the most important alkali raw material, the latter is the main component of sodium bicarbonate, Heating can be decomposed into sodium carbonate, carbon dioxide and water, because of the rich raw materials, simple process, so all the time to the modern still in use. “The washing stone is heated and decomposed, dissolved in water, and filtered to obtain a relatively pure sodium carbonate solution. ”

    “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, 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 content of «Elementary Chemistry». Due to the large number of two bases, they are easily confused (such as caustic soda, caustic soda, soda ash, baking soda, baking soda, soda, etc.), and it is an examination knowledge point. I didn’t have to recite the textbook related content at the beginning, so I still remember it so far.

    “I understand,” the chief alchemist looked at the reaction from beginning to end. “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 after the seed sourcing tour of the personal guard brought the olive tree seeds from Fallen Dragon Ridge, Border Town has 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 Leaf, and harvesting a bunch of fruit a day is not a problem.

    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 the fragments and the slag, and the clear oil can be obtained.

    After a brief explanation of the soap preparation and the requirement to retain glycerin, Roland left Cam Schuire to 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 smoke-free emission medicine and powerful explosives are not far from him.
