There are a number of methods for preparing calcium salts of carboxylic acids that are well known in the art and that could be initially considered in the instant situation. 请问: art在这里 是什么意思?可以翻译为“工艺”吗 and that could be initially considered in the instant situation.这里that指代的是哪个词? instant situation 什么意思 |

A process for the preparation of calcium salts(钙盐) of ketocarboxylic acids(酮酸) comprising: 一. reacting ketocarboxylic acids with an amine(胺), to afford( 以获得) a salt, said salt(所得的盐 ) being soluble in the reaction medium, 二. treating said salt with a source of calcium ion(钙离子) to afford the calcium salt of the ketocarboxylic acid, said salt being substantially insoluble in said reaction medium, 三. and isolating said calcium salt from the reaction medium. 该段定语短语的中心词就是A process ,其他都是描述限制这个process的。 |
