产品描述

乙酸丙酯(乙酸正丙酯)是乙酸的丙酯。 据报道,乙酸正丙酯与OH自由基反应的绝对速率常数为(k×10-9lmole-1s-1)= 2.6±0.5lmole-1s-1。 在各种温度(298.15、313.15和363.15K)下,对由水,乙酸和乙酸丙酯组成的三元体系的液-液平衡进行了研究。 发现实验值与UNIQUAC(UNIVERSAL QUAsiChemical)模型的实验值非常一致。 它已被鉴定为由青霉公社生产的挥发性酯之一。
乙酸丙酯可以用作溶剂,用于评估聚苯乙烯的聚合物溶液的蒸气压。 它可用于制备乙酸香叶酯。

General description

Propyl acetate (n-propyl acetate) is the propyl ester of acetic acid. The absolute rate constant for the reaction of n-propyl acetate with OH radicals has been reported to be (k × 10-9lmole-1s-1) = 2.6 ± 0.5lmole-1s-1.[3] Liquid-liquid equilibrium of the ternary system composed of water, acetic acid and propyl acetate has been investigated at various temperatures (298.15, 313.15 and 363.15K). Experimental values were found to be in close agreement with that of UNIQUAC (UNIversal QUAsiChemical) model.[4] It has been identified as one of the volatile ester produced from Penicillium commune.[1]

Application

Propyl acetate may be employed as a solvent for the evaluation of vapor pressure of the polymeric solution of polystyrene.[2] It may be used in the preparation of geranyl acetate.[5]
