IPC: C08B31/12
Filed: 1960-04-21
Abstract: The invention comprises sulphonium starch ethers.  These may have the formula: <FORM:0895406/IV (a)/1> wherein X is a starch residue, R1 is a radical selected from the group consisting of alkylene, hydroxyalkylene, aralkylene, cycloalkylene and phenylene radicals; each of R2 and R3 is a radical selected from the group alkyl, aryl, aralkyl, cycloalkyl and alkylene sulphonium radicals and any of the R2 and R3 radicals may also contain ether oxygen linkages and amino groups. and Y may be an anion.  The term starch includes nature starch, dextrins or hydrolysed, oxidized, esterified or etherified starch so long as the material still retains free hydroxyl groups. The starch may be derived from corn, potato, tapioca, waxy maize, sago or rice.  The etherification reagnent may be a halogenoalkyl sulphonium salt, a vinyl sulphonium salt, or an epoxy alkyl sulphonium salt of which the following are specified: 2-chloroethyl-methyl-ethyl sulphonium iodide; 2-chloroethyl-dimethyl sulphonium iodide; beta-chloroethyl-methyl-[2-(ethyl-methyl sulphonium)ethyl] sulphonium diiodide; vinyl-ethyl-methyl sulphonium iodide; dimethyl-2,3-epoxy propyl sulphonium iodide; dimethyl-p-chloromethylphenyl sulphonium iodide; methyl-cyclohexyl-chloroethyl sulphonium iodide; and benzyl-methyl-2-chloro-ethyl sulphonium iodide; and also the corresponding chlorides and bromides and bromoalkyl and iodoalkyl derivatives.  Reaction may be effected by suspending the starch in water to which has been added a base such as an alkali metal carbonate, alkali metal or alkaline earth hydroxide or a quaternary ammonium hydroxide and warming to 72 DEG  F. for 16 to 20 hours with constant agitation.  The product may be recovered by adding HCl to give a pH of 3 to 3,5 and then filtering.  It may be used as an adhesive, size or thickener.ALSO:Beta-halogenoalkyl sulphonium compounds are prepared by treating beta-hydroxyalkyl thioalkyl ethers with thionyl chloride and then the resulting halogenoalkyl thioalkyl ethers are isolated and alkylated by reaction with an alkylhalide to yield a beta-halogenoalkyl sulphonium salt or the corresponding aryl, aralkyl or cycloalkyl derivative.
