Title:
METHOD FOR MANUFACTURING TERT-BUTYL ALCOHOL FROM ISOBUTANOL, METHOD FOR MANUFACTURING METHACROLEIN AND METHACRYLIC ACID FROM ISOBUTANOL, AND MANUFACTURING DEVICE FOR SAID METHODS
Document Type and Number:
WIPO Patent Application WO/2013/069630
Kind Code:
A1
Abstract:
Disclosed are: a tert-Butyl alcohol manufacturing method that, in order to efficiently manufacture a methacrylic-resin feedstock from isobutanol, has a step (1) in which isobutanol is dehydrated to produce butenes and a step (2) in which said butenes are hydrated to produce tert-Butyl alcohol; a method for manufacturing methacrolein and methacrylic acid that has a further step (3) in which the aforementioned tert-Butyl alcohol is dehydrated and oxidized to produce methacrolein and methacrylic acid; and a device for performing steps (1) through (3).
