性质描述: 白色结晶或结晶性粉末。熔点115-118℃，沸点297-298℃。易溶于乙醇、乙醚和丙酮，微溶于水、氯仿、二硫化碳和石油醚。有轻微特殊香气，味微苦，灼麻。
生产方法: 由对羟基苯甲酸与乙醇在硫酸催化剂存在下进行酯化，酯化完成后在水中结晶，再经过滤、酸洗得成品。
用途: 有机中间体。用作防腐剂、抑菌剂，用于食品、化妆品、医药品。还可用作有机分析试剂。该品对霉菌、酵母与细菌有广泛的抗菌作用，对霉菌与酵母的作用较强，但对细菌特别是对革兰氏阴性杆菌及乳酸菌的作用较差。是食品和医药的高效防腐杀菌剂。

应用
Ethyl 4-hydroxybenzoate (ethylparaben) was used to study the? in-situderivatisation solid-phase microextraction procedure for determining parabens, related chlorophenols and triclosan in water. It is a novel sorbent for solid-phase extraction, was used to study its retention property. It has high extraction efficiency towards the compounds tested owing to the electrostatic interaction, hydrophobic interaction and hydrogen bonding.
