Preparation of new photosensitive material DBMPAZC for blue prints: Preparation of new photosensitive material DBMPAZC for blue prints. Liang, Dexiu (Beijing Chem. Eng. Fact., Beijing, Peop. 4858-52-0 and 615-67-8 are cas registry numbers. These chemicals are also mentioned in this article. Rep. China). Huaxue Shijie, 23(3), 70-1 (Chinese) 1982. CODEN: HUAKAB. ISSN: 0367-6358. DOCUMENT TYPE: Journal CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) The photosensitive compd. 2,5-dibutoxy-4-morpholinobenzenediazonium tetrachlorozincate (I)(DBMPAZC) [14726-58-0] was prepd. and was useful for blue prints. Treatment of hydroquinone [123-31-9] with (NH4)2Cr2O7 and H2SO4 gave benzoquinone [106-51-4] which was treated with HCl to form chlorohydroquinone (II) [615-67-8]. Alkylation of II with BuBr/NaOH gave 1-chloro-2,5-dibutoxybenzene [68052-10-8] which was treated with HNO3 to form 1-chloro-2,5-dibutoxy-4-nitrobenzene [89-30-5] and this was treated with morpholine [110-91-8] to give 1-morpholino-2,5-dibutoxy-4-nitrobenzene (III) [86-15-7]. 1-Morpholino-2,5-dibutoxy-4-aminobenzene [67828-46-0], prepd. by redn. of III, was treated with NaNO2 and HCl to give the diazonium chloride [4858-52-0] which was treated with ZnCl2 to form I. .
