通过脱羧、分馏等反应,可从腰果壳油中制得腰果酚。腰果酚是一种具有烯基不饱和C15碳链结构的苯酚衍生物,以其作为苯酚的取代物,采用曼尼希反应法可制成黏度低、使用期长、固化速率适中、固化物强韧性良好的新型曼尼希碱型EP(环氧树脂)固化剂。
By decarboxylation, fractionation and other reactions, from cashew nut shell liquid obtained in cardanol. Cardanol is a kind of phenol derivative with ethylenically unsaturated C15 carbon chain structure. Using it as a substitute for phenol, Mannich reaction method can be used to produce low viscosity, long service life, moderate curing rate and high curing strength Good toughness of the new Mannich alkali EP (epoxy resin) curing agent.
