Claim 1
Independent Claim
162 words
THE METHOD OF PREPARING ACYL TITANATES AND ORGANIC HALIDES WHICH COMPRISES MIXING AND HEATING AT TEMPERATURES IN THE RANGE OF FROM 100*C. TO 300*C. AND UNDER SUBSTANTIALLY AMHYDROUS CONDITIONS, AN ORGANIC ESTER HAVING A FORMULA SELECTED FROM THE GROUP CONSISTING OF R"OOCR AND R"OOC(R'')NCOOR''" IN WHICH R, R" ND R''" ARE UNIVALENT HYDROCARBON RADICALS, R'' IS A BIVALENT HYDROCARBON RADICAL AND N IS AN INTEGER OF FROM 0 TO 1 INCLUSIVELY, WITH AN ANFLUORIDOUS HALOTITANATE IN WHICH AT LEAST ONE TI-X BOND IS PRESENT AND WHERE X IS THE HALOGEN ATOM, AND IN WHICH THE REMAINING TITANIUM VALENCES ARE EACH SATISFIED BY BONDS THROUGH OXYGEN TO A MEMBER SELECTED FROM THE GROUP CONSISTING OF TITANIUM, HYDROCARBON, AND RC=O RADICALS IN WHICH R IS A HYDROCARBON GROUP, AND CONTINUING THE HEATING UNTIL ORGANIC ESTER LINKAGES ARE BROKEN AND AN ORGANIC HALIDE, DERIVED FROM AN ALCOHOL PORTION OF SAID ESTER, AND AN ACYL TITANATE, DERIVED FROM THE ACID PORTION OF SAID ESTER, ARE FORMED.
