METHOD OF PRODUCING FIREPROOF LIQUID Russian patent published in 1994 - IPC

Abstract RU 2016057 C1

FIELD: lubricants. SUBSTANCE: POCl₃ is etherified by mixture which contains, mass %: synthetic 3,5-xylenol 35-50, fraction of xylenols of coal tar (its boiling away temperature being 216-224 C) 18-22, phenol to 100. Ignition point thus prepared liquid is 800 C, solidification point is (-32 C), deaeration time is 90-105 s. EFFECT: improves deaeration properties, decreases solidification point. 2 tbl
