Derivatives of perfluorated carboxylic acids
Abstract
Abstract RT-CONH-(CH2)3-N(CH2CH2O)NH)2(R)X&, IN WHICH N IS A NUMBER FROM 1 TO 4, Z IS 1 OR 2, R REPRESENTS A LOWER ALKYL GROUP AND X- IS A HALOGEN SULFATE OR METHOSULFATE ANION, AND PROCESS FOR PREPARING THESE COMPOUNDS, WHEREIN PERFLUORO-ALKANE-CARBOXYLIC ACID ALKYL ESTERS, ARE REACTED WITH 1-(N,N-DIETHANOL)-3AMINO-PROPANE AND , DEPENDING ON THE COMPOUND, SUBSEQUENTLY OXETHYLATED, ESTERIFIED AND/OR QUATERNIZED. THE NEW COMPOUNDS STRONGLY REDUCE THE SURFACE TENSION OF AQUEOUS SOLUTIONS. THEY HAVE AN EXCELLENT WETTING POWER AND MAY ALSO BE USED AS EMULSIFIERS FOR FLUORO-HYROCARBON/WATER EMULSIONS. SURFACE-ACTIVE PERFLUORATED ALKANE-CARBOXYLIC ACIDAMIDE-AMINE DERIVATIVES AND THEIR QUATERNIZATION PRODUCTS OF THE FORMULAE D R A W I N G RT-CONH-(CH2)3-N(CH2CH2O)NH)2)(CH2)5C O O&), RT-CONH-(CH2)3-N(CH2CH2O)NH)2,
