National and provincial code:
CN320282
Abstract:
The invention discloses a process for preparing 2-methoxy-1-propanol acetate, which takes 2-methoxy-1-propanol and acetic acid as raw materials, and is characterized in that: the solid acid catalyst was used in the fixed-bed continuous esterification reaction, and the esterification temperature was 70-150 ℃. The water generated in the esterification reaction was removed by azeotropic distillation, the unreacted 2-methoxy-1-propanol and acetic acid were removed and recovered to obtain 2-methoxy-1-propanol acetate. The method of the invention realizes continuous production of 2-methoxy-1-propanol acetate, the operation mode is simple, the production efficiency of 2-methoxy-1-propanol acetate is significantly improved, and the production cost is reduced, and can reduce the solid pollutants and wastewater discharge, has excellent large-scale industrial application value.

2-methoxypropyl-1-acetate - Introduction
2-methoxy-1-propanol acetate (2-methoxypyl acetate) is a colorless liquid with a sweet and ether-like aroma. It is obtained by reacting 2-methoxy-1-propanol with acetic acid. The compound is insoluble in water and soluble in many organic solvents, such as alcohols, ethers and ketones.
2-Methoxy-1-propanol acetate has a wide range of uses in industry. It is an effective organic solvent and can be used in the formulation of paints, coatings, cleaners, inks, adhesives, etc. In addition, it can also be used as a diluent, extractant and reaction medium for polymers.
A common method for preparing 2-methoxy-1-propanol acetate is to esterify 2-methoxy-1-propanol with acetic acid in the presence of an acidic catalyst.
The compound is relatively safe under the correct conditions of use and storage. However, it is irritating and eye-irritating, so appropriate protective measures should be taken during use, such as wearing protective glasses and gloves. In case of accidental contact with skin or eyes, rinse immediately with plenty of water. During storage, avoid contact with oxidants and strong acids to avoid danger.
