Dependent Claim
193 words
A process for production of the surface-active organoboron compounds, comprising first reacting one mol of boric acid or triesterborate of monohydric lower alcohol with two mols of polyhydric alcohol having vicinal hydroxyl radicals in such a manner that the total number of hydroxyl radicals, in the molecules of said polyhydric alcohol is 5 or more per boron atom in the molecule of boric acid or per boron atom in the molecule of lower alcohol triborate thereby producing a triester borate of said polyhydric alcohol; then adding 1-40 mols ethylene oxide for attachment to one mol of thus obtained triesterborate of said polyhydric alcohol retaining at least one free hydroxyl radical besides the hydroxyl radical forming semi-polar bond in the presence of non-protonic Lewis acid catalyst in such a manner that the average degree of polymerization of the polyoxyethylene radical in the molecule of the end product is 1-40; and then reacting at least one of the terminal hydroxyl radicals of the derived triester borate with a carboxylic acid having alkyl groups having 7 to 31 carbon atoms or a lower alcohol ester of said carboxylic acid or an acylhalide of said carboxylic acid.
Claim 15
Dependent Claim
78 words
The process for the production of the surface-active organoboron compounds of claim 15, whereby 24 mols of ethylene oxide is subjected to the addition reaction using 3% by weight boron trifluoride as said catalyst, to one mol of a triester borate obtained from one mol of boric acid and two mols of glycerine; and then a carboxylic acid ester is derived through reaction with one to two mol of lauric acid, stearic acid, oleic acid or linoleic acid.
Claim 16
Dependent Claim
72 words
The process for production of the surface-active organoboron compounds in claim 15 whereby 24 mols of ethylene oxide is subjected to the addition reaction using 3% by weight boron trifluoride as catalyst, to one mol of a triester borate obtained from one mol of boric acid and two mols of glycerine; and then a carboxylic acid ester is derived through reaction with one mol of palmitic acid chloride or stearic acid chloride.
