Oxidation of 1-allyl-6- and -7-methylquinolinium iodides with potassium hexacyanoferrate(III) gave 1-allyl-6(7)-methylquinolin-2(1H)-ones which reacted with halogens to afford 2-halomethyl-7(8)- methyl-1,2-dihydro[1,3]oxazolo[3,2-a]quinolinium halides. 相似文献

A possibility of the immobilization of gentamicin on the surface of the polypropylene materials activated by the aqueous solution of hydrogen peroxide is studied. The polymers modified by biologically active materials are mainly the polymers of medical designation. Their basic function is exerting a complex of therapeutic actions in all phases (inflammation, regeneration and epitalization). Such materials in essence are used for preparing surgical seam threads, ambulance means, fixing bandages, prostheses of internal organs and tissues, etc. 相似文献

Results of investigations into the structural-phase state of éK-181 ferritic-martensitic low-activate steel after thermal
treatment including quenching, intermediate tempering, and subsequent long tempering under loading at temperatures of 923
and 973 K are presented. The influence of the defect substructure of the ferrite matrix, phase composition, and character
of the secondary dispersed phase distribution in the volume of the material on the heat-resistant steel properties is examined.

Summary The Soviet analysts' major advances in both theory and application of X-ray fluorescence (XRF) analysis are reviewed. The focus is on issues concerning XRF analysis of heterogeneous samples, a theoretical account of interelement effects, and employment of scattered radiation as the internal standard.
