THE PRODUCTION OF COLORED SMOKES FROM HIGHLY REACTIVE HYDROLYZABLE METAL CHLORIDES.
Abstract
Attempts to prepare concentrated titanium tetrachloride (TiC14) solutions containing organic dyes or colored inorganic compounds which, when released into the atmosphere, would produce colored smoke clouds were generally unsuccessful. All of the dyes and compounds either reacted with the TiC14 or were not soluble enough to color the TiC14 smoke. Several cyclic ethers and substituted phenols reacted to produce highly colored TiC14 substitution and addition compounds, some of which seemed readily soluble in TiC14. A number of these compounds reacted rapidly enough to produce colored smoke clouds by instant interaction with the TiC14. Chromyl chloride (CrO2C12) and vanadyl chloride (VOC13) were found to vaporize and hydrolyze with atmospheric moisture to form, respectively, a yellow chromium trioxide smoke and an orangecolored hydrated vanadium pentoxide smoke. A greater smoke density was obtained by mixing these compounds with TiC14. Several reducing agents were found which reacted with titanium tetrachloride, chromyl chloride, and vanadium oxytrichloride to produce violet, blue, and green smoke clouds. (Author)
