EFFECT OF PROTIC SOLVENTS ON THE FORMATIO N OF LYOTROPIC MESOPHASES OF TRIMETHYLAMINOACETIC ACID ESTER CHLORIDES IN BINARY-SYSTEMS

The phase diagrams of the following binary surfactant systems were exa mined by polarizing microscopy: trimethylaminoacetic acid decylester/w ater, trimethylaminoacetic acid decylester/ glycerol, trimethylaminoac etic acid decylester/butyleneglycol and trimethylaminoacetic acid dode cylester/water, trimethylaminoacetic acid dodecylester/glycerol, trime thylaminoacetic acid dodecylester/butyleneglycol. In all of these six binary phase diagrams the hexagonal phase, the lamellar and the isotro pic phase were observed. The formation of crystalline pha ses were dep endend on the solvents. The regions of the hexagonal phase H and the l amellar phase L were dependend on the solvents (water glycerol, butyle neglycol) and on the chain lengths of the ester groups.
