Efficient classical synthesis of aminoazines under microwave irradiation
In the present study, Aminoazines were prepared from the reaction of amidrazone hydroiodide with various aromatic aldehydes in the presence of a solid base under microwave irradiation with power level of 850 W for 2-7 min in high yields. The amidrazone hydroiodide can also be prepared by the reaction of S-methyl isothiobenzamide hydroiodide and hydrazine in methanol under nitrogen gas. All synt...
متن کاملSynthesis of Metallophthalocyanines Under Solvent Free Conditions Using Microwave Irradiation
Phthalocyanine complexes of Cu, Co, Ni, Fe, Zn, Pd, Pt and Ru have been synthesized from reaction between phthalonitrile and proper metal salts upon exposure to microwave irradiation under solvent-free conditions and considerably reduced reaction times.
متن کاملGlucoamylase immobilized on acid-hydrolyzed starch graft polyacrylonitrile.
A continuous stirred reactor fed maltose as substrate was used to show that acid hydrolyzed starch-g-polyacry-lonitrile and other polysaccharide graft copolymers can bind and retain significant quantities of active glucoamy-lase. Glucose productivities up to 2.7 g/g carrier/h were observed with the immobilized glucoamylase, and half-lives up to 1800 h were indicative of activity longevity. Fact...
متن کاملKINETICS AND MECHANISM OF GRAFT POLYMERIZATION OF ACRYLONITRILE ONTO STARCH INITIATED WITH POTASSIUM PERSULFATE
A new potassium persulfate redox system has been investigated for the graft polymerization of vinyl monomers. In this study potassium persulfate system was used for initiation the polymerization. Graft polymerization of acrylonitrile (AN) onto starch (Sta) was carried out in aqueous solution using potassium persulfate (I) redox system. It was found that the percentage of grafting and rate of gr...
