Compounds which dissolve in concentrated sulphuric acid may be further subdivided into those which are soluble in syrupy phosphoric acid (A) and those which are insoluble in this solvent (B) in general, dissolution takes place without the production of appreciable heat or colour. Those in class A include alcohols, esters, aldehydes, methyl ketones and cyclic ketones provided that they contain less than nine carbon atoms. The solubility limit is somewhat lower than this for ethers thus n-propyl ether di olves in 85 per cent, phosphoric acid but n-butyl ether and anisole do not. Ethyl benzoate and ethyl malonate are insoluble.

Sufficient sodium and benzophenone are used to produce a permanent deep blue color when the solution is refluxed under nitrogen e.g., for 400 ml. of crude n-propyl ether, 10 g. of benzophenone and 15 g. of sodium are usually sufficient. The ether is then distilled under a nitrogen atmosphere. 

When carried out under standard conditions with Et3SiH/TFA, reduction of acrolein leads to a mixture of allyl alcohol, 1-propanol, and di-n-propyl ether in addition to allyl trifluoroacetate and -propyl trifluoroacetate.434 The 1,2-reduction of cinnamaldehyde with triethoxysilane in the presence of fluoride ion provides the corresponding allyl alcohol in good yields (Eq. 261).
