Synthesis
1. Adipic acid method
(1), In the presence of barium hydroxide, dry distillation, convert adipic acid into cyclopentanone;
(2), By hydrogenation, obtain cyclopentanol;
(3), Sodium cyclopentyl sulfate is obtained by esterification of cyclopentanol and sulfur trioxide, neutralization with alkali (such as: sodium hydroxide).
Equation is as follows:
