반응 단계
α,α-Dimethylbenzylchloride was prepared by passing a stream of dry hydrogen chloride gas through a solution of methylene dichloride (750 ml.) and α-methylstyrene (500 g, 4.2 moles) at 4° C. The reaction and work-up were employed for the paration of 2,6-bis(1-isocyanato-1-methylethyl)naphthalene described in Example 4. The resulting monochloride was dissolved in 750 ml. methylene dichloride and was added to a cooled (4° C.) catalyst solution previously prepared from anhydrous, 90% sodium cyanate (389 g,5.39 moles), pyridine (50 ml., 0.633 mole), zinc chloride (39.15 g,0.28 mole) and 1 ml. H2O in 1075 ml methylene dichloride.
