Manufacturing Method of Methyl Waxy Acid
Methyl Waxy Acid is an important raw material for the production of chemicals, which is widely used in the fields of plastics, rubbers, coatings, inks and so on. In this article, we will introduce the manufacturing method of Methyl Waxy Acid, including the steps of raw material preparation, esterification reaction, distillation and purification.
I. Raw material preparation
The main raw materials for manufacturing methyl waxate are wax acid and methanol. Wax acid can be extracted from animal and plant oils and fats, and can also be prepared by chemical synthesis. Methanol is a common organic solvent which can be purchased in the market.
II.ESTERIFICATION
The esterification reaction is the key step in the manufacture of methyl wax acid. In the esterification reaction, wax acid and methanol react under the action of an acidic catalyst to form methyl ester of wax acid and water. Commonly used acidic catalysts include sulfuric acid and hydrochloric acid. The
esterification reaction is generally carried out under heated reflux conditions, which can facilitate the reaction. During the reaction, the acidity and ester content of the reaction solution need to be constantly monitored to determine the extent and end point of the reaction.
Three, distillation and purification
After the end of the reaction, the reaction solution needs to be distilled and purified to obtain the higher purity of methyl wax acid. Before distillation and purification, the catalyst and water in the reaction solution need to be removed to avoid the influence on the distillation process.
Distillation process, it is necessary to select suitable distillation conditions and equipment according to the physical properties such as boiling point and vapor pressure of methyl waxy acid ester to ensure the purity and yield of the product.
4. Precautions
1. In the manufacturing process, safety needs to be paid attention to avoid accidents such as fire and explosion.
2. In the process of raw material preparation and reaction, the quality and proportion of raw materials need to be strictly controlled to ensure the smooth progress of the reaction and the quality of the product.
3. In the process of distillation and purification, it is necessary to choose suitable distillation conditions and equipment to avoid product loss and quality degradation.
In short, the manufacturing method of methyl waxate requires certain chemical knowledge and skills, as well as attention to safety and product quality. Only by mastering the correct manufacturing method can we produce high quality Methyl Waxylate and provide reliable raw material guarantee for chemical production.
