1. the chemical synthesis process of a n-butyryl chloride is characterized in that:

  • this method is raw material with butanic acid with two (trichloromethyl) carbonic ethers, under the organic amine catalyst action in organic solvent 50~

    100 ℃

    of reaction 1~

    10h;

    Boil off organic solvent then under normal pressure, redistillation gets n-butyryl chloride;

    Butanic acid, two (trichloromethyl) carbonic ether are 1 ︰

    (0.33~

    3.0) ︰

    (0.01~

    1.0) with the amount of substance ratio of organic amine catalyzer;

    Described organic amine catalyzer is triethylamine, pyridine, N, dinethylformamide, N-methyl Pyrrolidine, tetramethyl guanidine, N-methylpyrrole, 1,3-dimethyl-2-imidazolidone, N,N-dimethylacetamide, tetramethyl-urea, N, one or more in the N-dibutyl formamide;

    Described organic solvent is one or more in benzene,toluene,xylene, chlorobenzene, dichlorobenzene, tetrahydrofuran (THF), ethyl acetate, trichloromethane, tetracol phenixin, normal hexane, hexanaphthene, Di Iso Propyl Ether, dibutyl ether, dioxan, the ethylene dichloride;

    The consumption of described organic solvent is 0.5~

    5 times of butanic acid quality.
