Quaternary sail

Group II. The classes 1 to 5 are usually soluble in dilute alkali and acid. Useful information may, however, be obtained by examining the behaviour of Sails to alkaline or acidic solvents. With a salt of a water-soluble base, the characteristic odour of an amine is usually apparent when it is treated with dilute alkali likewise, the salt of a water soluble, weak acid is decomposed by dilute hydrochloric acid or by concentrated sulphuric acid. The water-soluble salt of a water-insoluble acid or base will give a precipitate of either the free acid or the free base when treated with dilute acid or dilute alkali. The salts of sulphonic acids and of quaternary bases (R4NOH) are unaflFected by dilute sodium hydroxide or hydrochloric acid. 

Some of the chemical strategies used in weatherproofing have been applied to the preservation of cellulosics for indoor storage and display. The historical Wasa sails of 1628 were preserved by copolymerizing acrylates and styrene onto this material (36). Antimicrobial treatment of cotton goods by polymerization in situ of a urea-mercury compound with formaldehyde or immersion in a quaternary ammonium salt solution protected the fabric for up to three years storage provided it did not need to be laundered (37).

Alkyl azides. This quaternary ammonium sail is a suitable catalyst for the phase-transfer preparation of alkyl azides from alkyl bromides (iodides) and sodium azide in an aqueous medium yields are 74-93%.
