Antimisting agents

Abstract

Alkoxylated compounds of formula I R((AO)nH)mHp  (I) wherein each AO group is independently an alkyleneoxy group selected from ethyleneoxy, 1,2-propyleneoxy, 1,2-butyleneoxy, and styryleneoxy groups; n is an integer of from 2 to 100; m is an integer of from 1 to the total number of —OH plus —NH hydrogens in the R group prior to alkoxylation; the sum of m plus p equals the number of —OH plus —NH hydrogens in the R group prior to alkoxylation; and the R group is a group selected from the following: N(CH2CH2O)3  (II); R1N(CH2CH2O)2 where R1 is a C1-C24 alkyl, aryl, or aralkyl group  (III); R1N+(CH2CH2O)3Y− where R1 has the above meaning and  (IV) Y− is an anion, preferably an inorganic anion such as a halogen anion, a hydrogen sulfate anion, one-half of a sulfate anion, or one-third of a phosphate ion; NCH2CH2N  (V); NCH2CH2NCH2CH2N  (VI); CH3C(CH2O)3  (VII); CH3CH2C(CH2O)3  (VIII); C(CH2O)4  (IX); and where y is an integer of from 0 to 3, z is an integer of from 0 to 3, provided that the sum of y plus z is 2 or 3; and their use as anti-misting agents.
