Continuous-Flow Processing of Gaseous Ammonia Using a Teflon AF-2400 Tube-in-Tube Reactor: Synthesis of Thioureas and In-Line Titrations
摘要:
A simple tube-in-tube reactor based on the gas-permeable membrane Teflon AF-2400 was used in the continuous flow reaction of gaseous ammonia with isothiocyanates and one isocyanate. A colourimetric in-line titration technique is also reported as a simple method to quantify the amount of ammonia taken up by the solvent in the system.
3-amino-1H-1,2,4-triazole with the commercial aliphatic and aromaticisothiocyanates. The aliphatic isothiocyanate was used as reagent leading to substitution on NH atom of 3-aminotriazole ring, whereas the triazole amino group was substituted when isothiocyanate group was bonded to the Csp2 hybridized atom, e.g. an aryl or C=O fragment. All compounds were evaluated in vitro for the antimicrobial activity

3-(Substituted phenyl)imidazolidine-2-thiones (SPITs) and related compounds were synthesized by cyclizing monoethanolamine hydrogen sulfate with arylisothiocyanates in the presence of sodium hydroxide. The activity for stimulating adenylate cyclase prepared from thoracic nerve cords of the American cockroach, Periplaneta americana L., was examined with these compounds. A SPIT with a 2,6-diethylphenyl
