The present invention deals with substituted benzyl diketones and a process for their preparation.
Novel 2-(3',5'-dihydrocarbyl-4'-hydroxybenzyl)-1,3-diketones are prepared by reacting an N,N-dihydrocarbyl 2,6-dihydrocarbyl-4-aminomethylphenol with a 1,3-diketone and an alkyl halide in the presence of an alkali or an alkaline earth metal hydride.
The resulting substituted benzyl diketones are useful as antioxidants into polymers, latices, liquid hydrocarbon fuels and lubricating oils.
本发明涉及取代苄基二酮及其制备工艺。
新型 2-(3',5'-二氢羰基-4'-羟基苄基)-1,3-二酮是在碱或碱土金属氢化物存在下,通过 N,N-二氢羰基 2,6-二氢羰基-4-氨基甲基苯酚与 1,3-二酮和烷基卤化物反应制备的。
由此产生的取代苄基二酮类化合物可用作聚合物、乳液、液态烃燃料和润滑油的抗氧化剂。
