USE OF ADDITIONAL COMPOUNDS OF ETHYLENE OXIDE / PROPYLENE OXIDE OF GLYCERINE OR POLYGLYCERINE, REACTIONED WITH ALPHA-OLEPHINE EPOXIDES, AS DEFOAMERS.

摘要

THE USE OF PRODUCTS OF ADDITION OF GLYCERINE OR POLYGLYCERINE OF GENERAL FORMULA (I) [R] X (EO) N - (PO) M - (AO) P - H, IN WHICH [R] X IS A RADICAL OF GLYCERIN OR POLYGLYCERINE, AND EO IS A UNIT OF ETHYLENE OXIDE, PO IS A UNIT OF PROPYLENE OXIDE, AND AO IS A RADICAL OF FORMULA (II), WHERE R '' IS A RADICAL ALKYL LINEAR WITH 2 TO 18 ATOMS OF CARBON, X IS A NUMBER BETWEEN 1 AND 6, N IS A NUMBER BETWEEN 5 AND 60, M IS A NUMBER BETWEEN 30 AND 300, AND P IS A NUMBER BETWEEN 1 AND 10, OBTAINING IN THE COMPOUNDS OF FORMULA (I), MAKING THAT IN A FIRST STAGE N MOLES OF EO AND M MOLES OF PO PER MOL OF GLYCERINE OR POLYGLYCERINE ARE ADDED, AND IN A SECOND STAGE P MOLES OF ALPHA-OLEPHINE WITH 4 TO 20 ATOMS OF CARBON PER MOLECULA OF GLYCERIN O ALCOXYLATED, AS ANTI-FOAMS IN AQUEOUS SYSTEMS, FOR EXAMPLE IN THE FOOD, PAPER INDUSTRY, AS WELL AS PAINTS AND COLORANTS.
