1,4-CYCLOHEXANEDIMETHANOL DIBENZOATE synthesis

Yield:3412-68-8 96%

Reaction Conditions:

at 100 - 140; for 16 h;

Steps:

100 parts by weight of a CHDMDB isomer mixture containing about 70 weight percent trans-CHDMDB andabout 30 percent of the cis isomer, available as Benzoflex 352 (hereinafter referred to as "control"), were placed in anoven heated to a temperature of 140° C. The temperature of the oven was then lowered to 100° C. and maintained atthis temperature for 16 hours. The liquid portion of the composition was decanted, leaving a solid crystalline material.Analysis of the crystalline material by gas chromatography revealed a trans isomer content of 96 percent. This materialwill be referred to hereinafter as XP-7007
