Al(HSO4)3 is an efficient, readily available and cheap catalyst for thesynthesis of 1,3-benzo[d]thiazole derivatives by condensation of 2-aminothiophenol and 

In this video we'll balance the H2SO4 + Al(OH)3 = Al2(SO4)3 + H2O and provide the correct coefficients for each compound. To balance H2SO4 + Al(OH)3 = Al2( Abstract A mixture of ethyl formate and a catalytic amount of silica sulfuric acid or Al(HSO4)3 as suitable formylating systems can formylate various alcohols to their corresponding formate ester d 2008-05-09 · al + h2so4 ===> al2(so4)3 + h2o If my rows went in order Al, S, O, H, from top to bottom, and my columns went in the same order as the reaction is written above, my matrix would be the following: [-1 0 2 0 0] DOI: 10.1007/S00706-003-0083-4 Corpus ID: 97381558. Al(HSO4)3 as an Efficient Catalyst for the Acetylation of Alcohols in Solution and Under Solvent Free Conditions @article{Shirini2004AlHSO43AA, title={Al(HSO4)3 as an Efficient Catalyst for the Acetylation of Alcohols in Solution and Under Solvent Free Conditions}, author={F. Shirini and M. Zolfigol and M. Abedini}, journal={Monatshefte f{\"u Dihydropyridines were synthesized in good to excellent yields in the presence of NaNO2, Al(HSO4)3, and a catalytic amount of NaBr at room temperature. Low cost, the use of available reagents, simple methodology, and easy work-up procedure make this method attractive for organic synthesis.

Aluminum Sulfate Anhydrous is an aluminum salt with immune adjuvant activity. This agent adsorbs and precipitates protein antigens in solution; the resulting precipitate improves vaccine immunogenicity by facilitating the slow release of antigen from the vaccine depot formed at the site of inoculation.
