- CARBON MEMBRANE HAVING BIOLOGICAL MOLECULE IMMOBILIZED THEREON
-
Disclosed is a biological molecule-immobilized carbon membrane which comprises a porous carbon membrane and a biological molecule (e.g., an enzyme) immobilized on the carbon membrane, wherein the porous carbon membrane has three-dimensional cancellous pores through which fluid can permeate. The carbon membrane can have a large amount of a biological molecule (e.g., an enzyme) immobilized thereon and can also have a higher level of enzymatic activity or the like compared to a conventional one. Therefore, the carbon membrane is useful as an electrode for a bio-sensor or a bio-fuel cell.

- NONAQUEOUS SOLUTION OF HYPOCHLOROUS ACID AND CHLOROHYDRINATION REACTIONS OF CERTAIN LOWER ALKENES.
-
A study was made of the problems of preparing stable, highly concentrated nonaqueous solutions of hypochlorous acid and carrying out chlorohydrination reactions in them. The results on the chlorohydrination of alpha -alkenes showed that, in principle, it is possible and advisable to use solutions of hypochlorous acid in organic solvents, in particular, aliphatic and alicyclic ketones, ethyl acetate and tributyl phosphate. The use of organic solvents noticeably improves the stability of HOCl, so that the working concentrations of the acid can be increased, and the chlorohydrination reaction products can be more easily isolated.

- Three Component Reactions. XVI. Halogenation of Alk-1-enes in the Presence of Ethylene Oxide and Propylene Oxide
-
The products of the chlorination of alk-1-enes in the presence of ethylene oxide and propylene oxide were investigated in relation to products of the chlorination in the presence of corresponding chloroalcohols 4 and 5.Isomers dominating in the Markovnikov orientation were found in all cases.Two of the three pairs of diastereomeric bischloropropylethers expected for the chlorination of propene in the presence of propylene oxide were identified by capillar GLC and 13C n.m.r. spectroscopy.
