羧酸类 meaning in Chinese
carboxylic acids
Examples
- In carboxyl acid material vapors , the films had the highest sensitivity to the formic acid vapor
在羧酸类物质中又以对甲酸蒸气的响应灵敏度最高。 - Measurement to a series of organic vapors indicated that the films possessed fine response properties to carboxyl acid vapors
通过对多种有机蒸气的测量后发现，掺胺碳膜对羧酸类物质具有优良的选择性响应。 - Gas chromatography - mass spectrometry ( gc - ms ) analyses showed that both potassium permanganate and chlorine could oxidate the organic matters with unsaturated functional groups into those with carboxyl , hydroxyl and aldehyde . and it was further revealed that after preoxidation by potassium permanganate , the sorts of organic matters were reduced remarkably , however , chlorination leaded to increase of the sorts of orgnic matters and brought some chloro - organics such as chlorobenzene , chlorophenol , and trichloro - ethane
通过色谱-质谱联用( gc - ms )评价分析了高锰酸钾和氯对有机物结构的改变，高锰酸钾和氯均将原水中的一些不饱和性有机物氧化分解为一些含氧基团的有机物，如羧酸类、醇类和醛等有机物，但预氯化会在水中出现一些卤代物，卤代产物不仅出现在苯环上，而且出现在链烃上。 - In this paper , a new class of concrete high performance water reducer ( hpwr ) was designed from chemical classification of high performance wra , working principle and unit structure model of poly - carboxylate series wra . the comb - like copolymer structure of hpwr was " carboxylic group - ether link - ester link " . the synthetic chemical materials was polyethylene glycil , acrylic acid and methyl - metacrylic acid ester
本文从高性能减水剂的化学结构、作用机理以及聚羧酸类减水剂的单元结构模型出发，设计出国内所没有的一类新型高性能减水剂? ? “羧酸?醚键?酯键”为单元结构模型的梳型分子结构的减水剂共聚物，并确定了以聚乙二醇( peg )系列、丙烯酸( aa ) 、甲基丙烯酸甲酯( mma )为合成该类减水剂的主要化学原料。
