Chinese name : o acetoacetyl - Anisidine; 2-methoxy-N-Acetyl acetyl aniline; N - (2-methoxyphenyl) - 3-oxo - butyramide; acetyl acetyl-2-methoxy - aniline; acetoacetyl neighbors anisidine; o-methoxy - cetoactanilide

English name : o-Acetoacetanisidine; 2-Methoxy - N-acetoacetanilide; o-Acetoacetaniside; Acetoacetyl-2-anisidine; N - (2-methoxyphenyl) - 3-oxo - Butanamide; acetoacetyl-o-anisidin; 2'-methoxyacetoacetanilide; 2-acetoacetylaminoanisole; 2-methoxyacetoacetanilide; 2-methoxyanilid kyseliny acetoctove; acetoacet-o-anisidin

nature Description : white or nearly white crystals. 85-87 ° C melting point. Soluble in hot benzene and ethanol, ethanol-soluble cold.

production methods : to use both of the following routes. (1) from ethyl acetoacetate with neighbors anisidine derived role. First dry xylene; Ethylacetoacetate and triethanolamine ethanol solution heated to a boil-steamed, and a portion of xylene solution (at a temperature of 118-120 ° C), gradually warming up to 137-140 ° C, the collection xylene; Ethanol mixture cooled to 5-7 ° Ccrystal filter, with a little detergent in xylene crude, and then ethanol crystallization. (2) from neighbors and anisidine diketene reaction : Reactor into 500 parts water. Mixing strong adding 0.02 for Triphenyl Phosphine and 0.1 in N, N-dimethylaniline. In 45 minutes, stirring in under two pipelines (insert within the solution) were added to 90 diketene (purity 95.6%) and 1123 were neighbors anisidine (whichever speed Moore joined the other). Adequate cooling, the reaction temperature at 20 ° C. Reaction after another stirring 1h, in Slurry products. Its cooling to 10 ° C, filtration, drying, in the 192 white-o-anisidine cetoactanilide yield of 93%, 99.5%. Industrial production, but also enable the neighbors anisidine and diketene in ethanol medium, in the 20-25 ° C for condensation reaction.

purposes : for the goods dye intermediates. Yellow Light for the synthesis of dyes, direct light yellow 5G the azo components.
