答案解析: (a)(i) 该羧酸的摩尔质量为 60.0 g/mol,其中碳占 40.0%,氢占 6.67%,氧占 53.33%。根据质量百分比和元素的摩尔质量,可以计算出该羧酸的经验式为 C₂H₄O₂。由于经验式的摩尔质量与分子摩尔质量相同,因此该羧酸的分子式也为 C₂H₄O₂。 (a)(ii) 6.00 g 该羧酸的摩尔数为 0.1 ...
The invention relates to carboxylic acid derivates which contain at least one organically polymerisable group and at least one group which contains phosphorous and is reactive or wich modulates the properties of the molecule. The invention also relates to a method for production of the inventive mo...
A carboxylic acid reductase (CAR) from Mycobacterium marinum was found to convert a wide range of aliphatic fatty acids (C(6)-C(18)) into corresponding aldehydes. Together with the broad-substrate specificity of an aldehyde reductase or an aldehyde decarbonylase, the catalytic conversion of ...
