沸石 β

Zeolite beta is used in isomerization of waxes, and Friedel Crafts reactions (alkylation and acylation)Zeolite β, hydrogen is used as a molecular sieve, filter, adsorbent, catalyst, drying agent, cation exchanger, dispersing agent and detergent builder. It serves as an acid catalyst and utilized as an alternative to the known methods for protection of alcohols as tetrahydropyranyl ethers and the deprotection of tetrahydropyranyl ethers. It is also used in the stereoselective Meerwein-Ponndorf-Verley reduction of ketones. Further, it is used as an efficient and recyclable catalyst for the tetrahydropyranylation of alcohols and phenols.

Hygroscopic. Incompatible with strong acids, strong bases, hydrogen fluoride, chlorine trifluoride, ethylene oxide, halogenated hydrocarbon, oxygen difluoride, sodium nitrate, vinyl compounds, strong acids and strong oxidizing agents.
