METHOD FOR SEPARATING AND PURIFYING CRYSTALLISABLE ORGANIC COMPOUNDS

摘要

The invention relates to a process for separating and/or purifying organic compounds susceptible to crystallization by means of crystallizing and dissolving comprising the following steps:
a) depositing the composition in the head of a separation and/or crystallization column;
b) crystallizing by means of a cooling gradient;
c) pumping the solvent at optimal flow rate Fc;
d) entraining the components while they are not crystallized to the end of the column;
e) stopping the pumping of the solvent until reaching the lowest temperature of the interval established by the cooling gradient;
f) heating the column;
g) beginning new pumping by means of applying flow rate Fe;
h) collecting the eluates; and
i) detecting by means of detectors.
