TECHNOLOGY FOR THE PRODUCTION OF ACETONE DERIVATIVES
(DIACETONEALCOHOL, ISOPHORONE, HEXYLENEGLYCOL, METHYL ISOBUTYL CARBINOL)

PROCESS FEATURES

Apart of MIBK, CONSER, due to his collaboration with SISAS is in position to offer technologies for production of various acetone derivatives, including diacetone alcohol (DAA) isophorone (IPHO) hexyleneglycol (HG) from diacetone alcohol, methyl isobutyl carbinol (MIBC) from MIBK.

PROCESS DESCRIPTION

The technologies offered by CONSER are shortly described as follows:

DAA technology

Acetone is dimerized at low pressure and low temperature in presence of a basic catalyst in a reactor of tubular type. The crude product is then purified in a fractionation system comprising the recovery of non converted acetone, the separation of a fraction containing mesityl oxide, the separation of pure DAA.

IPHO technology

Acetone is reacted to IPHO in liquid phase, at pressure of about 50 bar, in presence of a basic catalyst. Crude product is then purified in a fractionation system comprising the recovery of non converted acetone, the separation of light and heavy ends to yield a purified IPHO.

HG and MIBC technology

Both products can be produced in the same unit in blocked operation.
HG is produced hydrogenating catalitically DAA at relatively high pressure.
MIBC is produced by hydrogenating MIBK at nearly identical conditions.
Both products are purified by fractionation.
