Ethyl acetate is the representative of ester,
There is no such thing as pure ethyl ester. There must be some kind of acid.
What is the main substance extracted from ethyl acetate?
Ethyl acetate is slightly soluble in water and soluble in most organic solvents such as alcohol, ketone, ether and chloroform, which proves that ethyl acetate can dissolve polar molecules such as ethanol and chloroform and nonpolar molecules such as ether. But personally, ethyl acetate has good solubility in nonpolar substances.
What is the composition of ethyl acetate?
Ethyl acetate, also called ethyl acetate, is a pure substance. But the ethyl acetate used in our industry is not pure. In addition to ethyl acetate, it also contains a small amount of impurities, such as ethanol, water, free acid and evaporation residue. In the process of preparing Hongchuan new material ethyl acetate, the percentage content of the above substances (except ethyl acetate) does not exceed 0.3%.
What is the difference between ethyl acetate and ethyl acetate?
What is the difference between ethyl acetate and ethyl acetate?
CH3COOH is acetic acid, commonly known as acetic acid. So acetic acid and acetic acid refer to the same substance.
2. The abbreviation of vinyl acetate is vinyl acetate. Structural abbreviation: CH3COOCH=CH2
Three. Vinyl acetate
4. Vinyl acetate polyvinyl acetate monomer.
Reference plane information:
Polyvinyl acetate
Polyvinyl acetate
Alias ethyl acetate resin
Code GB 07.00 1
Properties: white viscous liquid or yellowish fine powder or glassy block, smelly, transparent, strong toughness, soluble in water and fat, soluble in alcohols or lipids such as ethanol and ethyl acetate, easy to change color when exposed to light and heat, and has a promoting effect. The phase density is 1. 19(20℃) and the melting point is 100~250℃.
manufacture
(1) Ethylene, acetic acid and oxygen, vinyl acetate monomer and oxide catalyst are used to repolymerize polyvinyl acetate resin.
(2) The vinyl acetate monomer is polymerized by benzoyl oxide initiator at 70-90℃ for 2-6h to prepare polyvinyl alcohol powder.
What can distinguish ethyl acetate from hexane?
Distinguish ethyl acetate from hexane with NaOH solution.
Because ethyl acetate is completely hydrolyzed under alkaline conditions, ethanol and sodium acetate are generated and dissolved in water, so it is not layered. However, alkanes do not react with NaOH solution, are insoluble in water and are layered, and the upper layer is colorless oily liquid.
Chemical equation: ch3cooc2h5+NaOH-> >; CH3COONa+C2H5OH
