HG/T5626-2019 Methyl acetate for industrial use
HG/T5626-2019 Industrial Methyl Acetate Details:

Name: capillary column
Stationary phase: 6% nitrile propylphenyl 94% dimethylpolysiloxane,
Specifications: 60m*0.32mm*1.8um
Model: HH-62

Application: HG/T 5626-2019 Industrial Methyl Acetate



scope
This standard specifies the requirements, test methods, inspection rules and marking, packaging, transportation and storage of methyl acetate for industrial use.
This standard applies to the industrial methyl acetate produced by the polyvinyl alcohol industry and the industrial methyl acetate produced by the synthesis process of acetic acid and methanol.
Molecular formula: CH3COOCH3
Structural formula:

Relative molecular mass: 74.08 (according to 2016 relative atomic mass)

Type
Industrial methyl acetate is divided into: type I and type II. Type I includes methyl acetate by-product in the polyvinyl alcohol industry, and methyl acetate produced by the synthesis process of acetic acid and methanol. The purity of type I is ≥99.00%; type II is The by-product of the polyvinyl alcohol industry is industrial methyl acetate with a purity of ≥76.0%.

Require
Exterior
Colorless transparent liquid, no mechanical impurities.
Technical indicators
The quality of industrial methyl acetate should meet the technical indicators shown in Table 1
