摘要 |
FIELD: chemical industry. SUBSTANCE: present invention describes monoclinic crystalline alpha-modification of <EMI ID=0.79 HE=3 WI=15 TI=CHI>-nitrilo [thriethyl-tris-<EMI ID=0.80 HE=3 WI=18 TI=CHI>-(tetratert-butyl -<EMI ID=0.81 HE=3 WI=9 TI=CHI>- diphenyl -<EMI ID=0.82 HE=3 WI=9 TI=CHI>-diyl) phosphate], said compound is prepared by crystallization or transcrystallization from mixture of solvents based on any aromatic hydrocarbons and C<SB>1</SB>-C<SB>3</SB>- alkanol, or ether, ester or from mixture consisting of halogen substituted aliphatic hydrocarbon and C<SB>1</SB>-C<SB>3</SB>- alkanol. Said modification is used as stabilizer in stabilized composition in amount of from 0.01 to 10 wt % and comprises organic matter which is subjected to oxidative, thermal or light initiated destruction. Said modification is also used in stabilization method as stabilizer in amount from 0.01 to 10 wt %. EFFECT: improved properties of the stabilized composition. 21 cl, 4 tbl2
