Manufacturing Method of Ethyl Nitrile Propyl Acrylate
I. Introduction
Ethyl Nitrile Propyl Acrylate is an important raw material for the production of chemicals, which is widely used in the fields of polymer materials, pharmaceuticals, pesticides and so on. In this paper, we will introduce the manufacturing method of Ethyl Nitrile Acrylate, including raw material preparation, reaction steps, post-treatment and so on.
II. Raw material preparation
The following raw materials are needed to manufacture ethyl acrylate nitrile: acrylonitrile, ethyl acrylate, catalyst, polymerization inhibitor and so on. Among them, the mass ratio of acrylonitrile and ethyl acrylate is 1: (1-2), the dosage of catalyst is 0.1%-1% of the total mass of acrylonitrile and ethyl acrylate, and the dosage of polymerization inhibitor is 0.01%-0.1% of the total mass of acrylonitrile and ethyl acrylate.
III. REACTION STEPS
The manufacture of the ethyl acrylate nitrile adopts the method of copolymerization reaction, and the specific steps are as follows:
1. Mix acrylonitrile and ethyl acrylate according to a certain ratio, and add them to the reactor.
2. Add catalyst and polymerization inhibitor, and stir well.
3. Heating the reaction kettle, controlling the reaction temperature between 60-120°C and the reaction pressure between 0.1-1.0 MPa.
4. During the reaction process, the viscosity and acid value of the reaction solution need to be constantly monitored and adjusted as necessary.
5. At the end of the reaction, the reaction solution was cooled to room temperature to obtain the crude product of ethyl propyl acrylate nitrile.
4. Post-treatment
1. The crude product was filtered to remove impurities such as catalyst and polymerization blocker from it.
2. The filtered crude product was distilled, and the fractions were collected to obtain the product of ethyl acrylate nitrile with high purity.
3. Conduct quality inspection on the product and package it into storage after meeting the standard.
V. Precautions
1. During the manufacturing process, the reaction temperature and pressure need to be strictly controlled to ensure the safety and stability of the reaction.
2. Quality inspection of raw materials is needed to ensure that the purity and quality of raw materials meet the requirements.
3. In the post-treatment process, it is necessary to carry out sufficient quality inspection of the product to ensure that the quality and purity of the product meet the requirements.
VI.CONCLUSION
Ethyl acrylate nitrile is an important raw material for the production of chemicals, and the manufacturing method mainly includes the preparation of raw materials, reaction steps and post-treatment. The reaction conditions and raw material quality need to be strictly controlled during the manufacturing process to ensure that the quality and purity of the product meet the requirements.
