Customer Manager signature: 苯氧乙醇的性质、应用和合成 摘要:苯氧乙醇,别名乙二醇单苯醚,苯基溶纤剂,分子式:CHO,6102 结构式: OCHCHOH 22 苯氧乙醇是一种高沸点(低挥发溶剂。又是一种低致敏,高效(广 谱的防腐杀菌剂。由于它既能溶于水,又能溶于油中,所以近年来在 轻工,日化行业使用频度越来越高。国外对其应用研究甚多,尤其是 复合防腐剂中作为溶剂和协同剂,在很多产品中使用。我国在这方面 研究很少,为此研究它的合成、应用,很有现实意义和经济效益。 Phenoxy ethanol properties, preparation and application Abstract: phenoxyethanol, alias ethylene glycol monophenyl ether, phenyl cellosolve, molecular formula: CHO, structure type: 6102 OCHCHOH 22 Phenoxyethanol is a kind of high boiling point and low volatile solvents. It is a low sensitization, efficient broad-spectrum antiseptic. Because it can dissolve in water, and soluble in oil, so in recent years in light industry, chemical industry, more and more high use frequency. The application research of abroad very much, especially in preservative agent is used as a solvent and a synergistic agent, in many products used in. In our country it has rarely been studied, to study its synthesis, application, has very important practical significance and economic benefits. loan management (post) review: 1, approval criteria have been implemented; 2, the contract is correct; 3, in line with the contract, payment; 4, no other major cases against loan security;、Reviewed by: date of record form 9: qilu bank borrowing by single years of maximum amount a maximum no-loan borrowers: borrowers: ...
