Mercaptals mixed

In mixtures containing nitric acid various fuels may be employed. Fuels used for hypergolic ones, i.e. those which autoignite on mixing, differ essentially from those used in other mixtures. In hypergolic mixtures, fuels are used which reac. violently with nitric acid, e.g. aliphatic or aromatic amines, furfuryl alcohol, mercapt tans, hydrazine etc. It is also advisable to add surface-active substances to the mixture-... 

D-glucose mixed acetal, at least in the anomeric form employed, is not the probable intermediate in the formation of ethyl a-thio-D-glucofuran-oside from D-glucose diethyl mercaptal but that the mixed acetal is the probable intermediate in the formation of ethyl j3-D-galactofuranoside from D-galactose diethyl mercaptal. 

Mixed mercaptals are formed from -halo sulfides and thiols in yields up to 90%.331...

In their reaction with alcohols under acid catalysis, the aldoses differ from the simple, or unhydroxylated, aldehydes in forming mixed monocylic acetals (glycosides) rather than acyclic dialkyl acetals. However, Fischer 138) found that, on shaking a cold solution of an aldose in concentrated hydrochloric acid with a thiol, a crystalline product separated which was the dithioacetal (mercaptal) of the acyclic structure. These substances have... 

Reaction (a) is sufficiently definite to make possible the preparation of mixed mercaptals such as ethyl phenyl, ethyl benzyl and amyl phenyl Posner prepared these mixed mercaptals by treating one mol of mer-...
