sodium zeolite
2.Six surfactants,including methyl ester ethoxylate(MEE),alcohol ethoxylates carboxylate(AEC),betaine,alcohol ethoxylate 9(AEO_9),alpha olefin sulfonate(AOS),linear sodium alkyl benzene sulfonate (LAS),and four builders,HSST-1,3-AN,submicron zeolite 4A and zeolite 4A,are used for studying the effects on three alkaline proteases,YS-9412-130 low temperature alkaline protease,Properase 450E and Savinase 4.0T.
3.The catalytic synthesis of isoamyl butyrate with ferric chloride hex hydrate, stannous chloride dihydrate, aluminum sulphate octadecahydrate, sodium bisulfate monohydrate, p-toluene sulfuric acid, amino-sulfonic acid, solid super acid, heteropoly acid, strong acidic cationic exchange resin and HY zeolite molecular sieve are reviewed. Advantages and shortcomings as well as catalytic properties of each catalyst are analyzed.
4.This paper has summarized the researches on the application of such mineral materials as activated carbon, zeolite, montmorillonite, sepiolite, medical stone, palygorskite, aluminum oxide, sodium hydrate, alumen and nanomaterials as cigarette tip additives to the removal of harmful components in cigarette smoke in the last decades.
