Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
33 words
NEW COMPOUNDS, HYDROXY-, R-OXY-ALUMINUM CARBOXYLATES WHEREIN R IS A HYDROCARBON RADICAL THE HYDROXIDE OF WHICH IS LOW BOILING, AND THE MOL RATIO OF THE THREE SUBSTITUENTS ON THE ALUMINUM ATOM BEING APPROXIMATELY 1:1:1.
Claim 2
Dependent Claim
33 words
NEW COMPOUNDS, HYDROXY-, R-OXY-ALUMINUM CARBOXYLATES WHEREIN R IS A HYDROCARBON RADICAL THE HYDROXIDE OF WHICH IS LOW BOILING, AND THE MOL RATIO OF THE THREE SUBSTITUENTS ON THE ALUMINUM ATOM BEING APPROXIMATELY 1:1:1.
Claim 3
Dependent Claim
162 words
A PROCESS FOR PRODUCING HYDROXY-, R-OXY-ALUMINUM ACYLATES FROM ALUMINUM ALCOHOLATES AND PHENOLATES OF THE FORMULA A1(OR)3 WHEREIN R IS A HYDROCARBON RADICAL AND THE MOL RATIO OF THE THREE SUBSTITUENTS ON THE ALUMINUM ATOM BEING APPROXIMATELY 1:1:1 WHICH COMPRISES, FORMING AN INTIMATE LIQUID MIXTURE OF THE ALUMINUM COMPOUND WITH A MONOCARBOXYLIC ACID IN THE MOL RATIO OF APPROXIMATELY 1:1, SAID MONOCARBOXYLIC GROUP BEING FREE OF ANY FUNCTIONAL GROUPS WHICH WOULD INTERFERE WITH THE REACTIONS HEREINAFTER SPECIFIED, HEATING THE MIXTURE TO A TEMPERATURE AT WHICH REACTION PROCEEDS, COMPLETING THE REACTION DURING HEATING BY VAPORIZING OFF FROM THE REACTION MASS ABOUT ONE MOL OF HYDROXY HYDROCARBON LIBERATED BY THE REACTION, THEREBY FORMING A DI-ROXY-ALUMINUM MONOACYLATE, ADDING WATER TO SAID ACYLATE IN THE LIQUID STATE IN THE MOLAR RATIO OF APPROXIMATELY 1:1, INTIMATELY DISPERSING THE WATER THROUGHOUT THE MASS AND HEATING AND REACTING THE RESULTING MIXTURE UNTIL ABOUT ONE MOL OF HYDROXY HYDROCARBON IS LIBERATED AND VAPORIZED OFF, WHEREBY THE HYDROXY-, R-OXY-ALUMINUM ACYLATE IS OBTAINED.
