Isomerization of 1,2-difluoroethylene
Provided is a method for obtaining HFO-1132(E) and/or HFO-1132(Z) efficiently. The method is a method for producing HFO-1132(E) and/or HFO-1132(Z), comprising supplying a composition containing HFO-1132(E) and/or HFO-1132(Z) to a reactor, and performing an isomerization reaction between HFO-1132(E) and HFO-1132(Z).
1,3-BISISOCYANATOMETHYLCYCLOHEXANE COMPOSITION AND OPTICAL RESIN PREPARED THEREFROM
Disclosed is a 1,3-bisisocyanatomethylcyclohexane composition and an optical resin prepared therefrom. The composition comprises, based on the weight of 1,3-bisisocyanatomethylcyclohexane, a) 65%-95 wt % of trans-1,3-bisisocyanatomethylcyclohexane; b) greater than 0 and less than or equal to 0.5 wt %, preferably 0.02-0.5 wt % of 1,4-bisisocyanatomethylcyclohexane. Preferably, the 1,3-bisisocyanatomethylcyclohexane composition contains greater than 0 and less than or equal to 600 ppm of 1-isocyanatomethyl-3-methylcyclohexane, based on the weight of 1,3-bisisocyanatomethylcyclohexane. The 1,3-bisisocyanatomethylcyclohexane composition is used for preparing an optical resin, which can be applied to produce an optical lens with a better performance in preventing opacification and optical distortion.
