Title:
1-メトキシ-2-プロパノールの製造方法
Document Type and Number:
Japanese Patent JP5127263
Kind Code:
B2
Abstract:
To provide a manufacturing method of l-methoxy-2-propanol, which shows high conversion efficiency of propylene oxide and high selectivity of 1-methoxy-2-propanol and is capable of reducing by-product. Manufacturing 1-methoxy-2-propanol through a reaction step of reacting methane and propylene oxide at 90 to 110 DEG C to obtain a reaction crude liquid, and a distillation step of distilling the reaction crude liquid under the existence of tertiary amine. In the said method, the 1-methoxy-2-prpanol is manufactured by providing methanol, propylene oxide and tertiary amine to a column-type reactor equipped temperature controlling unit consisting of spiral tube capable of flowing heat-transferring-medium inside, and then the obtained crude liquid is distilled continuously at packed-column packed with structured packing.
