SANTOS, JOSE H. College of Arts and Sciences, University of the Philippines at Los Banos. March, 1987. Some Catalytic Properties of Mercury-Treated Coconut Husk Fiber in the Hydration of 2-Methyl-3-Butyn-2-ol.

Adviser: Dr. Prem Lath Maini

A comparative study was made using mercury-treated coconut husk fiber and different commercial solid supports which are capable of ion-exchange such as Dowex-50 resin, alumina, florisil, silica gel, cation-exchange cellulose, celite and molecular sieves. Previously washed and dried coconut husk fiber was ground to 40 and 100 mesh sizes. Cation-exchange capacity of untreated fiber was established and found to be 0.98 megig and 0.75 meq/g for 100 mesh and 40 mesh respectively. The meshed fiber was treated with 2M sulfuric acid and mercuric oxide solution successively according to Newman's procedure. The mercury-treated solid supports were stirred separately at room temperature for 24 hours to effect the hydration of 2-methyl-3-butyn-2-01 to 3-41ydroxy-3methy1-2-butanone. Results showed that mercurated coconut husk fiber can be used as an effective ion-exchange solid support for mercury in catalyzing the hydration of terminal acetylenic compounds. The mercurated coconut husk fiber, 100 mesh, has comparable high, efficiency in terms of yield of product (71.28%) as compared to mercurated Dowex-50 resin, which gave highest yield of 74.09%. Reaction product was identified by spectral analyses (infrared and proton magnetic resonance).
