Abstract:
A platinum complex represented by the formula: wherein R is a (C1 - 18) alkyl group, a (C1 - 18)-alkenyl group or a group @@ -X @@R in which X is -CH=CH- or a (C1 - 5) alkylene group, and R is a phenyl group, a hydroxyphenyl group, a (C7 - 12) alkoxyphenyl group, a halogenophenyl group, a nitrophenyl group, or (C8 - 13) alkoxycarbonylphenyl group, a cyclohexyl group having a (C1 - 5) alkyl substituent, R is a (C1 - 18) alkyl group, R is a hydrogen atom, or R and R are linked together to form a (C2 - 7) alkylene group; R is OH or NO3; the dotted line indicates that the bond may be either a single bond or a double bond; the chain line indicates a conjugated system; n is a number of from 1 to 2, and the 1,2-diaminocyclohexane moiety has a cis- trans- l - or trans-d-configuration. This platinum complex is useful in the treatment of tumors.
Abstract:
Fructose is effectively separated from a mixture of sugars by contacting an aqueous solution of a mixture of sugars with crystalline alumino-silicate.
Abstract:
Fructose sepn. from a sugar mixt., contg. fructose and glucose, is disclosed. Process takes place by selectively adsorbing an aq. charge soln. of the mixt. over a crystalline alumino-silicate, (I), so as to form a fructose-rich fraction which is sepd. (I) pref. has ave. pore dia. >5(5-15)angstroms. Highly pure fructose can be sepd. economically from a sugar soln. or from a cheap raw matl. contg. contaminants in addn. to fructose and glucose. Use of (I) having ave. pore dia. >5 angstroms allows a complete sepn. of fructose.
