biofiltration of triethylamine (tea) vapor used as a catalyst in casting operations was evaluated in this study. the unit consisted of a 6-l three-stage biofilter containing a mixture of compost and wood chips (40:60 v/v) as the filter medium. seed microbial population from municipal activated sludge was acclimated for a period of three weeks prior to the actual experimental runs. in the startu...

tetrahydropyranylation of alcohols and phenols, acetylation of aldehydes and n-boc protection of amines are efficiently catalyzed by melamine trisulfonic acid (mtsa). all reactions were performed at room temperature in good to high yields.

The imine podands tris[(2-nitrobenzylidene)aminoethyl]amine and tris[(2-nitrobenzylidene)aminopropyl]amine both stabilize copper(I), forming {tris[(2-nitrobenzylidene)aminoethyl]amine-kappa4N}copper(I) perchlorate acetonitrile disolvate, [Cu(C27H27N7O6)]ClO4.2CH3CN, (II), and {tris[(2-nitrobenzylidene)aminopropyl]amine-kappa4N}copper(I) perchlorate, [Cu(C30H33N7O6)]ClO4, (VI), respectively. The...

An account of the fundamental chemical and engineering principles solid amine-based CO 2 adsorbents their industrial application, with discussion relevance amine chemistry in utilisation technology.

copper amine oxidases (caos) catalyse the oxidative de-amination of biogenic amines which are ubiquitous compounds essential for cell growth and proliferation. the enzymes are homodimers containing both topaquinone and a cu(ii) ions as cofactors at the active site of each subunit. after extraction and purification of chickpea (cicer arietinum) amine oxidase by chromatoghraphy, km and vmax of th...

copper amine oxidases are important enzymes, which contribute to the regulation of mono- and polyamine levels. each monomer contains one cu(ii) ion and 2,4,5-trihydroxyphenylalanine (tpq) as cofactors. they catalyze the oxidative deamination of primary amines to aldehydes with a ping-pong mechanism consisting of a transamination. the mechanism is followed by the transfer of two electrons to mol...

Oxide-supported amine materials are widely known to be effective CO2 sorbents under simulated flue-gas and direct-air-capture conditions. Most work has focused on amine species loaded onto porous silica supports, though potential stability advantages may be offered through the use of porous alumina supports. Unlike silica materials, which are comparably inert, porous alumina materials can be tu...

Amine Prodrugs are being used since the beginning of the 19th century in medicines. Their Chemistry, Biological activity and Pharmacodynamic Characters has been revealed better in the 20th century. Most of the drugs that are invented in the recent century are prodrugs of amines, which show their importance in medical field. The purpose of this review is to focus on various aspects of amine prod...
