Chemical industry scale change development
1. Development overview of sec-butyl acetate industry
Sec-butyl acetate, also known as sec-butyl acetate, is one of the four isomers of butyl acetate, under normal temperature and pressure for colorless, flammable, with fruit flavor liquid, can be miscible in ethanol, ether and other most organic solvents.
Sec-butyl acetate is widely used in the nitrocellulose lacquer, acrylic paint, polyurethane paint, polyester paint, amino paint, epoxy paint coatings, such as solvent, can also be used for pesticide emulsifiable solution, synthetic resin, curing agent, solvent ink, adhesives and other chemical products; At the same time, in the pharmaceutical industry, fragrance industry, cleaning industry, fine chemical industry and gasoline blending group is also widely used, and can be used as butyl ketone, secondary butanol and other chemical products production raw materials; In addition, it can also be used as a high octane blending component of gasoline.
In recent years, the domestic productivity of sec-butyl acetate has been stable but rising, but the output has shown certain fluctuations, as follows:
One of the main reasons for the decline in the production of sec-butyl acetate in 2020 and 2021 is that, in addition to sec-butyl acetate, common solvents in the paint market include n-butyl acetate, ethyl acetate, toluene and xylene. Although sec-butyl acetate has advantages such as strong solubility, moderate volatilize rate, high extraction yield, low toxicity and little residue, some downstream customers tend to replace sec-butyl acetate with toluene and xylene at lower prices when its market price is higher than other related products.
2. Overview of isopropyl acetate industry development
Isopropyl acetate, also known as isopropyl acetate, is one of the two isomers of propyl acetate, at room temperature and pressure for colorless, flammable, with fruit flavor of liquid, alcohol, ketone, ether and other most organic solvents miscible. Isopropyl acetate is often used in pesticide and medicine, ink printing, dehydrating agent and other fields.
In recent years, the productivity and output of isopropyl acetate in China have been on the rise as follows:
3, butanone industry development overview
Butyl ketone, also known as methyl ethyl ketone or methyl ethyl ketone, is colorless transparent flammable liquid at normal temperature and pressure, volatile, similar to acetone odor, and ethanol, ether, benzene, chloroform, oil miscible. Butyl ketone is mainly used in adhesives, PU paste, coatings and other industries. PU paste is mainly used in the production of artificial leather, coatings are mainly used in the polyurethane and automotive industries, and adhesives are mainly used in the footwear industry.
In recent years, the domestic production capacity of butyl ketone has remained unchanged from 2018 to 2021, and increased by 80,000 tons to 837,000 tons in 2022. In terms of output, there is a certain trend of fluctuation.
