Abstract
THE PRESENT INVENTION IS A PROCESS FOR PURIFICATION OF 1,3-PROPANEDIOL (PDO) BY AN INVERTED DISTILLATION SEQUENCE WHICH COMPRISES: (A) OPTIONALLY REMOVING WATER OR OTHER SOLVENTS FROM THE CRUDE 1,3-PROPANEDIOL MIXTURE; (B) DISTILLING THE CRUDE 1,3-PROPANEDIOL MIXTURE (1) UNDER CONDITIONS WHICH MAXIMIZE THE SEPARATION OF COMPONENTS OF THE MIXTURE WHICH ARE HEAVIER THAN 1,3-PROPANEDIOL (4) FROM THE 1,3-PROPANEDIOL AND THE COMPONENTS WHICH ARE LIGHTER THAN1,3-PROPANEDIOL (4);(C) DRAWING OFF A STREAM (3) WHICH CONTAINS AT LEAST MOST OF THE 1,3-PROPANEDIOL AND AT LEAST SOME OF THE COMPONENTS OF THE MIXTURE WHICH ARE LIGHTER THAN 1,3-PROPANEDIOL; AND (D)DISTILLING THE STREAM OF (C) TO SEPARATE THE 1,3-PROPANEDIOL (6) FROM COMPONENTS IN THE STREAM WHICH ARE LIGHTER THAN 1,3-PROPANEDIOL AND ANY RESIDUAL COMPONENTS WHICH ARE HEAVIER THAN1,3-PROPANEDIOL (7A).(FIG 1)
