Abstract
Inventia se refera la un procedeu continuu de obtinere a 2-metil-2,4-pentandiolului prin hidrogenarea diacetonalcoolului la presiuni si temperaturi rdicate, conform caruia, în scopul obtinerii unei conversii mari la o selectivitate ridicata, se realizeaza hidrogenarea la presiune de 30-80 bari, temperatura de 80-140 degree C, în prezenta unui catalizator obtinut prin activarea aliajului de Cu-Al, la o încarcare specifica de 0,2-0,5 g diacetonalcool/cm cub catalizator ora.
