METHOD OF DEODORIZING TRIACETIN MANUFACTURED FROM NATURAL GLYCERINE

摘要

Process for deodorizing triacetin produced by the esterification of natural glycerin includes subjecting the triacetin to elevated temperature in the range of about 80 DEG to about 130 DEG C (preferably 90 DEG to 100 DEG C) while continuously sparging the triacetin with air or oxygen for between about 10 to about 36 hours (preferably 20 to about 24 hours).The process sufficiently removes odoriferous compounds from the triacetin, thereby producing an acceptable triacetin product of deodorized quality which is at least comparable to the deodorized quality of triacetin produced from synthetic glycerin and thus is suitable for use as a plasticizer in the production of cigarette filters from filamentary tow.
