Title:
不飽和カルボン酸エステルの製造方法
Document Type and Number:
Japanese Patent JP5188622
Kind Code:
B2
Abstract:
A process for preparing unsaturated carboxylic esters includes reaction of alkenes having 2 to 6 carbon atoms with alkanecarboxylic acids having 1 to 6 carbon atoms in the presence of an oxygenous gas and in the presence of a heterogeneous noble metal catalyst by means of a continuous homogeneous gas phase process in a reactor. A gaseous phase (cycle gas) is circulated, and the cycle gas is laden with alkanecarboxylic acid in an acid saturator before entry into the reactor. In a presaturator connected upstream of the acid saturator, the cycle gas is laden with a portion of the amount of alkanecarboxylic acid used for saturation, and then it is transferred to the acid saturator and laden there with the remaining amount of alkanecarboxylic acid.
