実験手順

1 mole triphenylchloromethane was stirred with 1.5 moles potassium acrylate in 998 g dimethyl formamide in the presence of 0.14 g hydroquinone under the conditions described in Example 1. The precipitated potassium chloride was filtered off and the triphenyl methyl acrylate solution was concentrated by rotary evaporation at 65° to 100° C. and reduced to produce liquid triphenylmethyl acrylate. This was dissolved at 70 percent in xylene and filtered.
