产品描述

Propionic acid is an important chemical raw material. Propionic acid and its derivatives are widely used in the synthesis of tree esters, grain preservation, food and feed additives, spices.
The earliest propionic acid was prepared by condensation and separation from the gas produced by charcoal manufacturing and coal coking. In the 1950s, foreign countries developed the process of producing acetic acid by oxidation of light hydrocarbons. The product contains about 10% (propionic acid), which is obtained after separation and purification. In addition to the hydrocarbon oxidation method, the United States also has the method of carbonylation of ethylene, CO and H2 to synthesize propionaldehyde and further oxidation to propionic acid. Due to the development of low-pressure carbonylation process with rhodium phosphine complex as catalyst, propionaldehyde oxidation method has developed rapidly in recent years. This method is superior to the traditional high-pressure method with carbonyl cobalt as catalyst.

应用

The global propionic acid market is divided by application, terminal industry and region. According to the application, the market is divided into herbicides, rubber products, plasticizers, food preservatives, etc., and food preservatives contribute the most to the market. Most people like the ready-to-eat food on the market. These foods contain propionic acid as an additive and preservative to maintain quality and reduce spoilage, which increases the demand for food preservatives. In addition, the surge in demand for food preservatives has promoted the growth of the global propionic acid market. Increasing demand for natural preservatives has driven the growth of this market.

1.Mainly used as food preservatives and antifungal agents.
2.It can also be used as an inhibitor of medium viscous substances such as beer.
3.Used as nitrocellulose solvent and plasticizer.
4.It is also used for the preparation of nickel plating solution.
5.The preparation of food spices, and antifungal agents.
