Manufacturing method of high carbon alcohol
I. INTRODUCTION
High carbon alcohol is an important class of raw materials for the production of chemicals, which is widely used in the fields of coatings, inks, detergents, plasticizers and so on. With the continuous development of science and technology, the manufacturing method of high carbon alcohol has been improved and optimized. In this paper, a common manufacturing method of high carbon alcohol will be introduced.
II. MATERIALS AND METHODS
1. MATERIALS
The raw materials required for this experiment mainly include: fatty acids, methanol, catalysts and so on.
2. Equipment
The experimental equipment includes: reactor, stirrer, heater, condenser and so on.
3. Manufacturing method
(1) Esterification reaction: Fatty acids and methanol were added into the reactor at the ratio of 1:3 molar ratio, catalyst was added, and the temperature was raised to 60-70℃ to carry out the esterification reaction. Constant stirring is required during the reaction to promote the uniformity of the reaction. After completion of the reaction, distillation was carried out to separate methanol and crude fatty acid methyl ester.
(2) Hydrogenation reaction: add crude fatty acid methyl ester and hydrogen at a molar ratio of 1:1 into a high-pressure reactor, add catalyst, raise the temperature to 200-240 ℃, and carry out hydrogenation reaction. A certain pressure and stirring speed need to be maintained during the reaction to ensure the smooth progress of the reaction. After the completion of the reaction, cooling and separation were carried out to obtain the high-carbon alcohol product.
III. RESULTS AND DISCUSSION
1. RESULTS
After the esterification reaction and hydrogenation reaction, we obtained high purity high-carbon alcohol products. All the indexes of the product meet the national standard and can be used in the production of chemicals.
2. Discussion
In the manufacturing process, we need to pay attention to the following points: firstly, the reaction temperature needs to be controlled in the esterification reaction to avoid too high or too low temperature affecting the reaction rate and product quality; secondly, a certain pressure and stirring speed need to be maintained in the hydrogenation reaction to ensure that the reaction proceeds homogeneously; and lastly, the product needs to be subjected to a rigorous quality inspection to ensure that it meets the relevant standards.
Fourth, Conclusion
In this paper, a common manufacturing method of high-carbon alcohols is introduced, through esterification reaction and hydrogenation reaction, we can get high-purity high-carbon alcohol products. This method has the advantages of easy operation, high production efficiency and stable product quality, which can be widely used in the field of chemical production. At the same time, we also need to pay attention to the details of the manufacturing process to ensure the quality and production efficiency of the product.
