Method of preparing dichloropropanols from glycerine |
摘要 |
A method of highly selective catalytic hydrochlorination of glycerine and/or monochloropropanediols to the dichloropropanol products 1,3-dichloro-2-propanol and 2,3-dichloro-1-propanol, carried out in at least one continuous reaction zone at reaction temperatures in the range of 70-140° C. and with continuous removing of the water of reaction, the liquid feed containing at least 50% by weight of glycerine and/or monochloropropanediols. The method can be carried out in a continuously operating one-step circulation reactor or a cascade of continuous flow reactors of the liquid-gas type.
