Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. Electric Literature of 1111-67-7. Introducing a new discovery about 1111-67-7, Name is Cuprous thiocyanate
The coordination polymers .infin.(1)[CuBr(1,7-phen-kappaN7)] (1a), [CuI(1,7-phen)] (2a) and [(CuI)2(1,7-phen-kappaN7)] (2b) may be prepared by treatment of the appropriate copper(I) halide with 1,7-phenanthroline(1,7-phen) in acetonitrile. 1a exhibits staircase CuBr double chains, 2 a novel quadruple CuI chains. Their thermal properties were investigatedby DTA-TG and temperature resolved powder X-ray diffraction. On heating , both 1:1 compounds decompose to 2:1 polymers and then finally to CuBr or CuI. With 4,7-phenanthroline (4,7-phen), CuBr affords both 1:1 and 2:1 complexes (5a, 5b), CuI 1:1, 2:1 and 3:1 complexes (6a, 6b, 6c) in acetonitrile at 20°C. 5a and 6a display lamellar coordination networks, with the former containing zigzag CuBr single chains, the latter 4-membered (CuI)2 rings. A second 2:1 complex .infin.(2)[(CuI)2(4,7-phen-mu-N4,N7)] (6b’) with staircase CuI double chains can be obtained by reacting CuI with 4,7-phen in a sealed glass tube at 110°C. Both 5a and 6a exhibit thermal decomposition pathways of the general type 1:1 2:1 3:1 CuX, and novel CuX triple chains are proposedfor the isostructural 3:1 polymers 5c and 6c. X-ray structures are repo rted for complexes 1a, 2b, .infin(2)[(CuCN)3(CH3CN)(1,7-phen-mu-N1,N7)] (3c*CH3CN), .infin.(1)[CuSCN(1,7-phen-kappaN7)] (4a), 5a, 6a and .infin.(2)[CuCN(4,7-phen-mu-N4,N7)] (7a).
The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 1111-67-7
