This invention relates to an improved adsorbent comprising a crystalline aluminosilicate, method of manufacture of the adsorbent and improved process for separating a component from a feed mixture comprising an aqueous solution of a mixture of different components, such as a mixture of saccharides. In the process the mixture is contacted with the adsorbent, which selectively adsorbs a component from the feed mixture. The adsorbed component is then recovered by contacting the adsorbent with a desorbent material such as water to effect the desorption of the adsorbed component from the adsorbent. There is an undesirable tendency for the silicon constituent of the crystalline aluminosilicate to dissolve in the aqueous system. The improvement to the adsorbent and process comprises the incorporation of a binder material in the adsorbent comprising a cellulose ether which substantially reduces the undesirable dissolution. The adsorbent is manufactured by mixing together powder of the crystalline aluminosilicate, powders of the binder, and a liquid organic solvent, extruding the mixture into an extrudate and drying the extrudate.

A process is disclosed for the production of monochloro- and aryl-substituted saturated compounds which comprises condensing an alkyl aromatic hydrocarbon containing from 1 to 10 carbon atoms in the alkyl substituent with a monochloromonoolefin possessing up to 14 carbon atoms and having the chlorine attached to one of the doubly-bonded carbon atoms in the presence of a free radical-generating catalyst.

Production of monochloro- and aryl substituted saturated compounds

Monochloro-substituted saturated compounds may be prepared by condensing a saturated compound such as cycloalkyl hydrocarbon with a chloromonoolefin possessing not more than 4 carbon atoms and having the chlorine atom attached to one of the doubly-bonded carbon atoms in the presence of a free radical-generating catalyst and a promoter comprising a hydrogen chloride compound.

Production of monochloro-substituted saturated compounds

Monochloro-substituted saturated compounds are prepared by condensing an aliphatic saturated hydrocarbon containing a secondary of tertiary carbon atom with a monochloromonoolefin possessing up to 14 carbon atoms and having the chlorine atom attached to one of the doubly-bonded carbon atoms in the presence of a free radical-generating catalyst.

Non-ionic biodegradable detergents as exemplified by n-alkyl-substituted hydroxypolyalkoxymethylcyclohexanes may be prepared by condensing butadiene with allyl alcohol, selectively hydrogenating the resulting compound to form hydroxymethylcyclohexane, ring alkylating said substituted cyclohexane with an olefin in the presence of a free-radical generating compound to form an alkyl-substituted hydroxymethylcyclohexane and thereafter alkoxylating this compound to form the desired product.

Non-ionic biodegradable detergents comprising n-alkyl-substituted hydroxypolyalkoxymethylcyclohexenes may be prepared by condensing butadiene with allyl alcohol, thereafter ring alkylating the resultant hydroxymethylcyclohexene with an olefin in the presence of a free-radical generating compound to form an alkyl-substituted hydroxymethylcyclohexene and alkoxylating this compound to form the desired product.

Anionic biodegradable detergents as exemplified by alkaline sulfate esters of n-alkyl-substituted hydroxypolyalkoxymethylcyclohexenes may be prepared by condensing butadiene with allyl alcohol, ring alkylating the resultant hydroxymethylcyclohexene with an olefin in the presence of a free-radical generating compound to form an alkyl-substituted hydroxymethylcyclohexene, alkoxylating this compound to form an alkyl-substituted hydroxypolyalkoxymethylcyclohexene, sulfating the latter compound and neutralizing the sulfate ester with an alkaline material to form the desired product.

Novel compositions of matter which are useful as biodegradable detergents comprise alkali metal disubstituted cyclohexenyl sulfates. These compounds are prepared by condensing butadiene with allyl chloride, thereafter ring alkylating the resultant chloromethylcyclohexene with an olefin in the presence of a free-radical generating compound and reacting the disubstituted cyclohexene with an alkali metal salt of a sulfur-containing compound to form the desired product.
