Abstract: A catalyst for production of 1,6-hexanediol is prepared via co precipitation technology in a 50 L scale-up batch reactor.The performance of the catalyst is appraised through catalytic hydrogenation of dimethyl adipate in a high temperature and high pressure fixed bed reactor.Influences of reaction temperature,pressure,gas hourly space velocity and molar ratio between hydrogen and ester on the hydrogenation reaction are investigated.The results show that the conversion rate of dimethyl adipate can exceed 99% and the yield of 1,6-hexanediol can reach above 97% when the reaction temperature is at 230-250℃,the pressure is 5-8 MPa,the gas hourly space velocity is 6 151-12 300 h-1,the molar ratio between hydrogen and ester is larger than 150 and liquid hourly space velocity is 0.3-0.6 h-1.
