Description

  1. Product Overview

乙酸乙酯(醋酸乙酯)为无色透明、易挥发液体,具有醚样果香气味(菠萝香型),是应用最广的酯类有机溶剂之一。微溶于水,与乙醇、丙酮、乙醚、氯仿、苯等多数有机溶剂互溶。

Ethyl acetate (acetic ester) is a colorless, clear, volatile liquid with an ether-like fruity (pineapple) odor. It is one of the most widely used ester solvents. Slightly soluble in water; miscible with ethanol, acetone, ether, chloroform, benzene and most organic solvents.

广泛应用于油墨、涂料、油漆、人造革、胶黏剂、塑料制品、医药(萃取剂/反应介质)、食用香料(GB 2760 允许使用)及化妆品等领域;亦为分析试剂与色谱(GC/HPLC)标准溶剂。

Widely used in printing inks, coatings, paints, artificial leather, adhesives, plastics, pharmaceuticals (extraction/reaction medium), food flavoring (per GB 2760) and cosmetics; also an analytical reagent and chromatography (GC/HPLC) standard solvent.
