BORON-SILICON COMPOUNDS SUITABLE FOR USE AS HYDRAULIC FLUIDS

摘要

After B(OH)3 is reacted with HO-(R50)n-R6, the product is then reacted with R2SiX2Y to manuf. boron-silicon compd.(I). R1 is hydrocarbyl, -(OR5)nOR6, -R5(OR5)nOR6, or (II). R2 is as R1 or O(R50) n Si(R1)2. Each R3 or R4 is (III), -B(O(R5)n-R6)2, or -(R50)nR6. R5 is alkylene or arylene . R6 is H or hydrocarbyl. n is 0 or an integer. Y is a halogen atom. X is halogen atom or R1.
