Abstract
Abstract The reaction rate of a directed interesterification reaction is accelerated by subjecting a glyceride mixture alternately to a temperature of 1*-15*C below the cloud point of a randomised mixture of the same glycerides and to a temperature of at least the cloud point of said randomised mixture. The temperature is cycled at least three times until the cloud point of the mixture obtained is at least 5*C above the cloud point of the randomised mixture.

Total Claims: 8
Claim 1
Independent Claim
133 words
PROCESS FOR ACCELERATING THE DIRECTED INTERESTERIFICATION REACTION OF A MIXTURE OF GLYCERIDES CONTAINING FATTY ACID RADICALS WITH 2 TO 26 CARBON ATOMS, IN WHICH THE REACTION IS CARRIED OUT AT TEMPERATURES FROM -30* TO 60*C IN THE PRESENCE OF 0.01 TO 0.5% BY WEIGHT OF ALKALI METALS OR THEIR CATALYTICALLY ACTIVE DERIVATIVES UNDER CONDITIONS AT WHICH THE GLYCERIDE MIXTURE IS ALTERNATIVELY SUBJECTED FOR 5 TO 60 MINUTES TO A TEMPERATURE 1* TO 15*C BELOW THE CLOUD POINT OF A RANDOMIZED MIXTURE OF THE SAME GLYCERIDES AND FOR 15 TO 300 MINUTES TO A TEMPERATURE OF AT LEAST THE CLOUD POINT OF SAID RANDOMIZED MIXTURE, WHEREBY THE TEMPERARURE IS CYCLID AT LEAST THREE TIMES UNTIL THE CLOUD POINT OF THE MIXTURE OBTAINED IS AT LEAST 5*C ABOVE THE CLOUD POINT OF THE RANDOMIZED MIXTURE.
