Brief Introduction

Diene ketone has strong reaction ability and can be derived from a variety of products. It is the raw material of fine chemicals, dyes, pharmaceuticals, pesticides, food and feed additives and additives. Acetyl diethylamine obtained by reaction of diene and diethylamine is an intermediate of organophosphorus insecticide phosphoramine; Acetylmethylamine obtained by reaction with methylamine is the intermediate of monocrotophos. Dienone reacts with ammonia to produce acetylacetamide, which is used to synthesize dye intermediates 1 - (4-chlorophenyl) - 3-methyl-5-pyrazolone and 1 - (4-sulfonylphenyl) - 3-methyl-5-pyrazolone; Dienone reacts with ethanol to produce ethyl acetoacetate, which is used to synthesize dye intermediates such as 1-phenyl-3-methyl-5-pyrazolone, 1 - (2,5-dichloro-4-sulfonylphenyl) - 3-methyl-5-pyrazolone, etc. From these intermediates, dye YONGGU yellow G, acid mordant jujube BN, neutral orange RL, neutral brown 5rl, neutral dark brown BRL, acid light yellow G, weak acid light yellow G, acid light yellow 2G, active light yellow k-6g, active light yellow m-5g, active light yellow x-6g, neutral peach BL, etc. can be prepared. 1-phenyl-3-methyl-5-pyrazolone and its derivatives are more used in the production of antipyretic analgesics antipyrine, aminopyrine, analgin, etc. Diene ketones can also be used in the synthesis of amino acids. Feed additive quinoethanol (kuaiyuling) can be prepared from diene, o-nitroaniline and ethanolamine. Dienes are used to synthesize a variety of heterocyclic compounds, such as pyrrole derivatives, isoxazole derivatives, pyrazolone derivatives, pyrimidine derivatives, thiazole derivatives, quinoline compounds, coumarin compounds and furan derivatives; Dienone can also react with a series of compounds to produce pyranone, pyridinone, dioxane, oxazine and flavonoids. Used as pharmaceutical intermediates, food preservatives, pigments and regulators.
