Liquid organic scintillators are important devices for measurements of neutron radiation. Currently, large-scale liquid have capabilities detecting neutrons, but the determination energy spectra is a challenge. This work aims to measure responses two two-component mono-energetic radiation and determine their light output function, which necessary proper determination. Both composed solvent di-i...

A new series of 1-[(2, 5-dichloroanilinomalonyl)-3-(N-2’-cyanoethyl)-2-(Ncinnamoyl) 2, 5-dichloroanilino)]-5phenyl pyrazoline have been synthesized in 49 to 66% yield, by the reaction of N-cinnamoyl-N-2’-cyanoethyl-2,5dichloroaniline with 2-[(Ncinnamoyl) 2,5-dichloroanilido] acetohydrazide. Pyrazolines are yellow, cream and brown color solids, having high melting points. Identity of these produ...

Abstract. Biotransformations are chemical reactions carried out by microorganisms on organic substrates. can be regio-, chemo-, stereo- and enantio-selective. Bioreductions of great interest to the food pharmaceutical industries as they help reduce costs impacts environment. In this work, following biotransformations chalcones were performed: (2E)-1-(4-hydroxy-phenyl)-3-(2-methoxy-phenyl)-prop-...

In the title mol-ecule, C(17)H(14)ClFN(2)O, the mean plane of the pyrazoline ring makes dihedral angles of 18.19 (1) and 83.51 (4)° with the 4-chloro-benzene and 4-fluoro-benzene rings, respectively. The two benzene rings make a dihedral angle of 76.11 (2)°. Weak inter-molecular C-H⋯O hydrogen bonds help stabilize the crystal structure.

In the title compound, C(17)H(18)N(4)OS, a pyrazoline derivative, the pyrazoline ring adopts an envelope conformation with the C atom bonded to the benzene ring as the flap atom. The dihedral angle between the pyridine and benzene rings is 80.50 (6)°. The eth-oxy-phenyl group is approximately planar, with an r.m.s. deviation of 0.0238 (1) Å for the nine non-H atoms. In the crystal, mol-ecules a...
