The manufacturing method
of butyl formate
1. Introduction
Butyl formate is a common chemical production raw material, widely used in paints, coatings, printing inks, spices and other industries. This article will introduce the manufacturing method of butyl formate, including raw material preparation, reaction process, post-treatment and so on.
2. Raw Material Preparation
The main raw materials for the manufacture of butyl formate are formic acid and n-butanol. In the process of raw material preparation, it is necessary to ensure the purity and quality of raw materials to avoid adverse effects on subsequent reactions.
3. reaction process
The manufacturing process of butyl formate is mainly an esterification reaction, that is, under the action of acidic catalyst, formic acid and n-butanol react to produce butyl formate and water. The following are specific reaction steps:
1. formic acid and n-butanol are added into a reaction kettle according to a certain molar ratio, and an appropriate amount of acidic catalyst is added at the same time.
2. Open the stirring, so that the raw materials are fully mixed.
3. heating the reaction kettle, control a certain reaction temperature, so that the reaction.
4. Monitor the progress of the reaction and stop heating when the yield of butyl formate reaches a certain value.
4. post-treatment
After the end of the
reaction, a post-treatment is required to obtain a pure butyl formate product. The post-treatment mainly includes the following steps:
1. cooling the reaction kettle and cooling the reaction solution to room temperature.
2. Unreacted formic acid and n-butanol can be separated by distillation or extraction.
3. The butyl formate is refined to remove the impurities.
4. Finally, the product quality inspection shall be carried out, and the packaging shall be put into storage after meeting the standards.
Precautions for
5.
1. During the manufacturing process, the ratio of raw materials and reaction temperature should be strictly controlled to avoid side reactions.
2. The choice of acid catalyst has an important influence on the reaction rate and yield, and the appropriate catalyst should be selected according to the actual situation.
3. In the post-processing process, attention should be paid to operating specifications and safety to avoid product pollution and personal injury.
6. conclusion The manufacturing method of
butyl formate mainly includes the steps of raw material preparation, reaction process and post-treatment. By controlling the ratio of raw materials, reaction temperature and the choice of catalyst, high-quality butyl formate products can be obtained. In the post-processing process, attention should be paid to operating specifications and safety to ensure product quality and production safety.
