<p>New phosphobetaine compounds of the formula
<CHEM>
Wherein A is selected from OH, OM and OYR
B is selected from OH and OM
R is an imidazoline reactant moiety of the formula
<CHEM>
<??>Wherein R3 is alkyl, alkenyl, alkoxy, hydroxyalkyl or hydroxyalkenyl of 2 to 20 carbon atoms each or R3 is aryl or akylaryl or cycloaliphatic of up to 20 carbon atoms each.
<??>R1 and R2 are individually selected from hydrogen, propionic acid, propionitrile, propionamide, propionate esters of C1-C12 alkyl, alkylaryl or alkylcycloaliphatic or alkali metal or alkaline earth metal salts or amine salts of propionic acid with the proviso that when R1 is hydrogen R2 must be a propionate derivative.
<??>Y is alkylene of 2 to 12 carbon atoms optionally interrupted by up to 3 oxygen atoms.
<??>M is hydrogen, alkali metal, alkaline earth metal, amine or RY are highly stable and posses interesting properties as surfactants and hydrotropes. </p> |
