Title:
【発明の名称】ガス分散反応器を用いたトリエチルアミン触媒作用によるネオペンチルグリコールの製造
Document Type and Number:
Japanese Patent JPH03504235
Kind Code:
A
Abstract:
A process for producing neopentyl glycol is disclosed which comprises reacting isobutyraldehyde and formaldehyde in the presence of a trialkylamine catalyst to form a condensation reaction product comprising hydroxypivaldehyde, followed by hydrogenation of the hydroxypivaldehyde in a hydrogen gas sparged reactor in the presence of a Raney nickel catalyst. This process minimizes unwanted by-products, and does not have to be carried out under high pressure as do certain prior art methods.
