STABILIZATION OF LIQUID SULFUR TRIOXIDE

摘要

INVENTION: STABILIZATION OF LIQUID SULFUR TRIOXIDE INVENTORS: ANTHONY W. YODIS FRANK J. KREMERS KAROL K. LINTERN Liquid sulfur trioxide is stabilized against polymerization by incorporating therein a stabilizer combination of a normally liquid siloxane polymer with a methyl ester of an acid of boron. The siloxane polymer and the methyl ester of the acid of boron are each employed in an amount of at least 0.01 percent by weight of the sulfur trioxide.
