Yield:1724-39-6 97%
Reaction Conditions:
with hydrogen;palladium on activated charcoal at 220; under 67991.1 Torr; for 12 h;
Steps:
11
In an example, 40 grams of product collected from a process according to Example 8 are subjected to a distillation process according to Example 10. A fraction collected between 145-155° C. is transferred to a high pressure autoclave. A hydrogen reduction catalyst comprising palladium on carbon is introduced. The autoclave is sealed, the air is displaced completely with hydrogen gas and the autoclave is heated to 220° C. Additional hydrogen gas is provided and the pressure is maintained at 1300 psig (ca. 9000 kPa absolute) for 12 hours. The autoclave is cooled to 100° C., a sample is taken for analysis and transferred into a glass reactor prior to solidification. The sample taken is identified as cyclododecanol (CDDA) having a purity of 98.5%, the yield is 97%.
