The title compound, C(32)H(28)N(2)O, is a flexible Schiff base displaying a trans configuration across the C=N double bond. It was prepared in high yield by condensation of α-methyl-cinnamaldehyde and bis-(4-amino-phen-yl) ether in methanol at room temperature. The sample, with pseudo-ortho-rhom-bic cell parameters, exhibited merohedral twinning by rotation 180° around a*, with a refined twin d...
The title compound, C(26)H(24)N(2)O(3), was synthesized by reduction of the corresponding Schiff base. The mol-ecule does not possess crystallographic or non-crystallographic symmetry. The dihedral angle between the oxygen-bridged benzene rings is 67.98 (8)°. Both hydroxyl groups are involved in O-H⋯O intra-molecular hydrogen bonding. The mol-ecules are linked into a two-dimensional network par...
Data were last reviewed in IARC (1986) and the compound was classified in IARC Monographs Supplement 7 (1987). 1.1.2 Structural and molecular formulae and relative molecular mass C 6 H 12 Cl 2 O Relative molecular mass: 171.7 1.1.3 Physical properties (for details, see IARC, 1986) (a) Boiling-point: 187°C (b) Melting-point: –100°C (c) Conversion factor: mg/m 3 = 7.02 × ppm 1.2 Production, use a...
This work presents the results of studying behavior catalytic systems formed on basis trichlorotris-(tetrahydrofuranate)chromium(III) in presence sulfur-containing tridentate SOS-type ligands and activated by various organoaluminum compounds. In formation systems, following compounds were used: - bis-(2-methylthioethyl) ether, bis-(2-ethylthioethyl) ether bis-(2-phenylthioethyl) triethylaluminu...
Bis(2-chloro-1-methylethyl) ether is a beta-haloether and a byproduct of propylene oxide and propylene glycol manufacture. A bioassay of technical grade bis(2-chloro-1-methylethyl) ether for possible carcinogenicity was conducted by administering the test chemical by gavage to F344 rats. Groups of 50 rats of each sex were administered a solution of bis(2-chloro-1-methylethyl) ether in corn oil ...
