    Critical temperatures and pressures of straight-chain alkanediols (C3 to C12) [Electronic resource] / E. D. Nikitin, A. P. Popov, N. S. Bogatishcheva, V. A. Kuznetsov // Fluid Phase Equilibria. - 2013. - Vol. 355. - С. 40-45. - Bibliogr. : p. 45 (32 ref.)

CRITICAL PROPERTIES -- THERMALLY UNSTABLE COMPOUNDS -- ALKANEDIOLS
Аннотация: The critical pressures pc and the critical temperatures Tc of diols with straight alkylchains HO(CH2)nOH and n = 3, 4, 5, 6, 8, 9, 10, 12 have been measured. All the alkanediols studied decompose at near-critical temperatures. A pulse-heating method which allows measuring the critical properties of thermally unstable compounds has been used. The times of heating from the beginning of a pulse to the moment of reaching the critical temperature were from (0.03 to 0.46) ms. The short residence times provided little degradation of the substances in the course of the experiments. The uncertainties of the measurement of the critical properties of alkanediols are 0.04 pc and 0.015 Tc, where Tc is the absolute temperature. The critical properties obtained have been compared with the values measured earlier by various techniques. The experimental critical constants of alkanediols have also been compared with those calculated using the group-contribution methods of Lydersen, Wilson and Jasperson, and Marrero and Gani

    Selective reduction of derivatives of fluorinated beta-diketones [Text] / O. G. Khomutov, V. I. Filyakova, K. I. Pashkevich // Journal of Fluorine Chemistry. - 1992. - Vol. 58, № 2-3. - P351

Аннотация: The reduction of fluorinated ?-diketones (DK) is known to give ?-diols [G. Swalens, M. Anteunis and D. Tavernier, Bull. Soc. Chim. Belg., 79 (1970) 441–450] and ?-hydroxyketones (HK) II [A.L. Henne and P.E. Hinkamp, J. Am. Chem. Soc., 76 (1954) 5147]. We have established that the lithium salts (Ia) as well as chelate compounds of DK with zinc (Ib) and aluminium (Ic) undergo selective reduction with LiAlh4 to HK III. Salts (Id) and chelate compounds (If) are not reduced under the same conditions

CHLORINE DIOXIDE -- OXIDATION -- SELECTIVITY
Аннотация: Oxidative dehydrogenation of vicinal diols of bornane and pinane type with chlorine dioxide in dimethylformamide has yielded α-hydroxyketones with high selectivity. 3α-Hydroxy-10β-pinane-4-one has been prepared for the first time with yield of 63-65%; the product structure has been confirmed by X-ray diffraction studies

Аннотация: The system chlorine dioxide-dimethylformamide in combination with or without a catalytic amount of MoCl5, CeCl3, ZrOCl2, or VO(acac)(2) induces oxidative chlorination of a number of bicyclic terpene alcohols and vicinal diols. 2 alpha-Chloropinan-3-one, 3 alpha-chloro-10 beta-pinan-4-one, 5 alpha-chloro-3 alpha-hydroxycaran-4-one, 5 beta-chloro-3 beta-hydroxycaran-4-one, and 4 alpha-chloro-2 alpha-hydroxypinan-3-one were thus synthesized in good preparative yields.

ORGANOSILICON COMPOUNDS -- DIOLS -- GLYCEROL
Аннотация: Biologically active hydrogels based on silicon polyolates, which are the products of reactions of tetraethoxy- and methyltriethoxysilanes with polyols (1,2-propanediol, glycerol, polyethylene glycol), were synthesized. The optimal conditions for hydrogel formation and hydrogel composition were determined. The acute toxicity and transcutaneous and wound-healing activities of the synthesized compounds were studied. The experimental results show that hydrogels based on silicon polyolates can be recommended for further preclinical and clinical tests with the purpose of their use in medical practice both as self-sufficient agents and ointment bases of pharmaceutical compositions with wound-healing, regenerative, and transcutaneous action
