FLAME RETARDANT COMPRISING AROMATIC PHOSPHATE ESTER-BASED COMPOUND, AND METHOD FOR PREPARING SAME

摘要

A method for preparing a novel aromatic phosphate ester-based compound, including: (a) reacting a compound expressed by chemical formula 1 (i) and a C6-10 aryl compound substituted with hydroxy or C1-6 alkoxy, or a C6-20 arylalkyl compound substituted with hydroxy or C1-6 alkoxy (ii), which are used as reaction materials by gradually heating to the temperature levels of 90-125° C., 125-180° C., 180-210° C. and 210-240° C.; (b) separating an aromatic phosphate ester-based compound from the resultant product in step (a) under the condition of a pressure of 0.01 mmHg-50 mmHg and a temperature of 50° C.-300° C. using fractional distillation; and (c) reacting the aromatic phosphate ester-based compound separated in step (b) (i) and C1-10 alcohol or a nitrogen compound (ii) at a temperature of 10-70° C.

1. A method for preparing an aromatic phosphate ester-based compound comprising the steps of:
(a) reacting a compound expressed by a chemical formula 1 (i) and a C6-10 aryl compound substituted with hydroxy or C1-6 alkoxy, or a C6-20 arylalkyl compound substituted with hydroxy or C1-6 alkoxy (ii), which are used as reaction materials by gradually heating to the temperature levels of 90-125° C., 125-180° C., 180-210° C. and 210-240° C.; (b) separating an aromatic phosphate ester-based compound from the resultant product of the step (a) under the condition of a pressure of 0.01 mmHg-50 mmHg and a temperature of 50° C.-300° C. by using fractional distillation; and (c) reacting the aromatic phosphate ester-based compound separated in the step (b) (i) and C1-10 alcohol or a nitrogen compound (ii) at a temperature of 10-70° C.; wherein R1, R2 and R3 of the chemical formula 1 are, respectively and independently, halo (i), C6-10 aryl substituted with hydroxy or C1-6 alkoxy (ii), or C6-20 arylalkyl substituted with hydroxy or C1-6 alkoxy (iii); and one or more of R1, R2 and R3 is halo.
