Separation. — The separation of thorium from the rare earth metals with which it is still mixed may be accomplished by three methods (1) the carbonate separation depends on the fact that thorium carbonate is much more soluble in sodium carbonate than the carbonates of the rare earth metals (2) by the fractional crystallization of the mixed sulfates at 15°-20°, crystals of Th(S04)2 8 H20 are obtained at the insoluble end of the series (3) thorium oxalate forms a soluble double salt with ammonium oxalate, while the rare earth oxalates are almost insoluble in this reagent. Some other methods which have been suggested are fractionation of the chromates,4 of the hydrogen alkyl sulfates,5 of the acetates, by the use of sebacic add 6 and hydrogen peroxide.

The reduction of aryl alkyl tellurium dihalides in which the alkyl group bears an electronegative substituent (chlorine, oxygen) on the /1-carbon, cleaves the alkyl group and forms diaryl ditellurium compounds. Sodium sulfide4-6, sodium hydrogen sulfite, hydrazine sulfate, and zinc effect this conversion. 

The presence of the hydrogen carbonate is necessary to liberate the base from the amine (alkyl sulfate) salt, so that this also may be further methylated. Sodium hydrogen carbonate has the advantage over a stronger base for this purpose in that the pH that results permits selective alkylation of aminophenols on nitrogen.834...

Sodium alkyl sulfates are esters. Thus sodium dodecyl sulfate is sensitive towards hydrolysis, especially in acid solutions. In this case, the starting fatty alcohol and sodium hydrogen sulfate is formed. Hydrolysis, once started, will run autocatalytically because the sodium hydrogen sulfate formed in this reaction is an acid in itself. Alkyl sulfates are stable in storage when in their highly pure states. 

To use sodium alkyl sulfate as a standard material, one has to ensure that the substance does not contain any impurities. One of the ways to create such a pure substance is to use the reaction of n-dodecanol with an adduct of chlorosulfuric acid and diethyl ether. The fatty alcohol is added to the ether solution while being cooled with ice. A stoichiometric surplus of 5-10% of chlorosulfuric acid is used to avoid forming the dialkyl sulfuric acid ester. The major part of the hydrogen chloride gas formed will evaporate. 

The chlorosulfonic acid-ether complex is a milder reagent than free chlorosulfonic acid for the sulfation of alcohols and is outstanding in respect of yield and purity of the alkyl hydrogen sulfates 45 produced. The use of chlorosulfonic acid in diethyl ether at low temperature (-50 °C) is a standard method for sulfation of higher (Cg-C28) primary and secondary alcohols. The latter have also been successfully sulfated using a mixture of chlorosulfonic acid in acetic acid the active entity here is probably acetyl sulfate. This method has been adapted for the synthesis of very pure sodium alkyl sulfates for use as detergents thus chlorosulfonic acid and 1-dodecanol were successively added to acetic acid at low temperature (—10 to -15 °C), the solid product was neutralized with sodium carbonate and unreacted alcohols extracted with solvents to give 98.6% pure dodecanyl sodium sulfate. ... 

Sodium alkyl glucoside sulfates containing 10-14 carbon atoms are useful surfactants in shampoos. They were prepared by stirring the appropriate a,/ -glucoside with chlorosulfonic acid in chloroform at 15 °C for 1 hour, followed by neutralization with aqueous sodium hydrogen carbonate. ...
