| abstract | Pentachlorperylene is made by passing chlorine through a suspension or solution of perylene in benzyl chloride, carbon tetrachloride, or glacial acetic acid. 2-(3<1>-Aminophenyl)-5-aminobenzoxazole is obtained by heating 2 : 4-dinitrophenol with 3-nitrobenzoyl chloride and reducing the resultant ester. The almost colourless crystals have a M.P. of about 240 DEG C.ALSO:Aliphatic hydrocarbons such as ligroin, petrol, benzine and paraffin oil are rendered fluorescent, and thus "marked" as products of a particular manufacturer, by incorporating a small proportion, e.g. 0.05 per cent, of an amino - 2 - phenylbenzthiazole, an amino - 2-phenyl-benzoxazole, or a perylene or a perylene derivative, which is insoluble in water or alkalies. Perylene derivatives specified are acyl-, aryl-, aroyl- and halogenated perylenes and perylene nitrites. In examples, (1) 1000 litres of benzene is given a reddish blue fluorescence by adding 4 litres of a 2 per cent solution of dehydrothiotoluidine in benzene; a blue by adding dehydrothioxylidine in benzene; a greenish-blue by adding 2 litres of 0.2 per cent solution of primuline base in tetrahydronaphthalene; (2) 100 litres of benzene is given a blue fluorescence by incorporating 2 gm. of 2-(3<1>-aminophenyl)-5-aminobenzoxazole as a solution in benzene or tetrahydro-naphthalene; (3) a blue-green fluorescence is imparted to 100 litres of dark paraffin oil by 500 gm. of perylene; a green by 500 gm. of 3 : 9-dichlorperylene, 3 : 9-dibromperylene, or pentachlorperylene; (4) mineral oil with a blue fluorescence is given a green fluorescence by incorporating 0.05 per cent of 3 : 9-diacetylperylene, 3 : 9-dipropionylperylene, 3 : 9-dibenzoyl-perylene, or 3 : 9-di-(o- or p-chlorbenzoyl) perylene. Pentachlor-perylene is made by passing chlorine through a suspension or solution of perylene in benzyl chloride, carbon tetrachloride, or glacial acetic acid. 2-(3<1> - aminophenyl) - 5 - aminobenzoxazole is obtained by heating 2 : 4-dinitrophenol with 3-nitrobenzoyl chloride and reducing the resulting ester. The almost colourless crystals have a M.P. of about 240 DEG C. According to the Provisional Specification commercial liquid hydrocarbons such as benzol, benzine, petroleum distillates, and hydrogenated hydrocarbons are rendered fluorescent by adding small quantities of derivatives of thiazole, oxazole or perylene or its derivatives. |
