    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.

    Abstract: 1391618 Perfluorocarboxylic acid derivatives HOECHST AG 2 June 1972 [2 June 1971] 25903/72 Heading C2C [Also in Division B1] Novel perfluorocarboxylic acid derivatives of formula RfCO.NH.(CH 2 ) 3 .Y where Rf is an unbranched C 6 -C 10 perfluoroalkyl group and Y is a group of formulae -N[(CH 2 CH 2 O) n H] 2 , [(CH 2 ) q COO - ] or where R is C 1 -C 4 alkyl, X- is a halogen, sulphate or methosulphate anion, n is 1-5 and q is 1 or 2, are prepared by reacting an alkyl perfluoroalkanoate of formula RfCOOR‹ where R‹ is alkyl, with N,N-di-#-hydroxyethylpropylenediamine followed by optional etherification, esterification, or quaternization. The novel derivatives are used as melting and dispersing agents and as emulsifiers.
