METHOD OF 4-BIPHENYLMETACRYLATE OBTAINMENT Russian patent published in 2009 - IPC C07C67/08 C07C67/10 C07C69/54 C07C69/618 

FIELD: chemistry.

SUBSTANCE: invention concerns organic compound synthesis, particularly method of obtaining 4-biphenylmetacrylate of the formula . Obtained compound is applied in production of heat and weather resistant polymer materials. Claimed method involves dissolution of 4-phenylphenol in 10 wt % aqueous solution of caustic soda, further dosage of acylating agent in the form of metacrylic acid anhydride agent in reaction mix preliminarily cooled to 0-(+5°)C at such rate so as to keep the mix temperature below +10°C at molar ratio of 4-phenylphenol and metacrylic acid anhydride of 1:(1.1-1.5), reaction mix maturing at room temperature with stirring, organic layer extraction, flushing by alkali solution, and drying.

EFFECT: enhanced output of 4-biphenylmetacrylate, admixture content of non-reacted 4-phenylphenol reduced to 0,003-0,005 wt %.
