Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates 网页Methyl diethanolamine. Molecular Formula CHNO. Average mass 119.162 Da. Monoisotopic mass 119.094627 Da. ChemSpider ID 7479. 网页Triethanolamine (TEA) A colorless to yellow liquid. It is completely soluble in water and has an ammonia-like smell. Building block in the manufacture of triazine based corrosion inhibitors. It is commonly used as a cement grinding aid, and can be used in other applications as well. Diethanolamine (DEA) 网页2010年1月1日 The incorporation of small amounts of tertiary alkanolamines such as triethanolamine (TEA), triisopropanolamine (TIPA), diethanol-isopropanolamine (DEIPA), methyl-diethanolamine (MDEA) is common 网页2003年10月1日 The introduction of grinding aids (GA) started more than fifty years ago; it has as its ultimate objective decreasing the energy consumption to obtain a given fineness or flow of cement. Studies 网页Gas Sweetening. Maurice I. Stewart Jr. PhD, PE, in Surface Production Operations (Third Edition), Volume 2, 2014 9.5.2.8 MDEA Systems 9.5.2.8.1 General Discussion. MDEA is a tertiary amine, which, like the other amines, is used to sweeten natural gas streams. Major advantage over other amine processes is MDEA can be used to selectivity remove H 2 S 网页Sep 01, 2020 Heren and lmez studied the effects of monoethanolamine (MEA), diethanolamine (DEA) and triethanolamine (TEA) on the setting time and tensile and flexural strengths of concrete in three cement replacement levels (0.1%, 0.5% and 1%) and a constant w/c ratio of 0.4. 网页2020年7月6日 chemical mixture for concrete, to a grinding aid for the fine grinding of minerals such as limestone, coal, slag, clinker, silica.
