标题:一种电子级没食子酸辛酯的制备方法
摘要:本发明提供了一种电子级没食子酸辛酯的制备方法,属于有机合成技术领域.采用没食子酸溶解在醇中,随后滴加氯化亚砜成酯,接着再加入芳烃溶剂,催化量b(C6F5)3和正辛醇,通过酯交换将醇蒸馏后,得到没食子酸辛酯.此方法避免了重金属催化剂的使用,收率高,成本低廉,适合工业化放大生产,在酯交换结束后加入金属离子吸附剂将金属离子吸附后,蒸馏得到电子级别的没食子酸辛酯.

摘要:According to the invention, there is provided null-LOX-1 barley and plant products produced thereof, such as malt manufactured by using barley kernels defective in synthesis of the fatty acid-converting enzyme lipoxygenase-1. Said enzyme accounts for the principal activity related to conversion of linoleic acid into 9-hydroperoxy octadecadienoic acid, a lipoxygenase pathway metabolite, which-through further enzymatic or spontaneous reactions-may lead to the appearance of trans-2-nonenal. The invention enables brewers to produce a beer devoid of detectable trans-2-nonenal-specific off flavors, even after prolonged storage of the beverage.
