Nowadays, ultramarine-type pigments are produced synthetically. Inside the zeolite structure the highly reactive sulfur radical anions are well protected which explains the stability of the blue color over thousands of years in air. However, the species responsible for the blue color should not be confused with the sulfur radical cations responsible for the blue color of sulfur solutions in fuming sulfuric acid (oleum) and similar oxidizing mixtures... 

Since the oxides do not have to be isolated, the sulfur solution after addition of the peroxyacid solution is simply kept in the refrigerator until S,(, has formed which is then isolated by cooling and recrystallization When both Sg and S g are dissolved in CS and the solution is cooled, then, under special concentration conditions, a new sulfur allotrope crystallizes out as orange-yellow opaque crystals of m.p. 92 °C. This compound has been shown by vibrational spectroscopy and X-ray structural analysis to consist of equal amounts of Sg and molecules in their usual conformations. In solution the mean molecular weight of 258 corresponding to 8 atoms per molecule indicates complete dissociation This is the first example of an allotrope of a chemical element consisting of molecules of different sizes. 

Glycerine Nitrate or Nitroglycerin (NG). Accdg to Ref 2, NG may be destroyed by the so-called sulfur solution , which is prepd by dissolving S in aq Na carbonate soln. Accdg to Mellor (Ref 5a), S dissolves in Na carbonate with formation of polysulfide, thiosulfate and carbon dioxide ... 

Description Propylene, ammonia, and air are fed to a fluidized bed reactor to produce acrylonitrile (ACRN) using DuPont s proprietary catalyst system. Other useful products from the reaction are hydrogen cyanide (HCN) and acetonitrile (ACE). The reaction is highly exothermic and heat is recovered from the reactor by producing high-pressure steam. The reactor effluent is quenched and neutralized with a sulfuric solution to remove the excess ammonia. 

When aqueous sulfide solutions are heated with sulfur, solutions containing largely S2 and S2" are obtained. These polysulfide ions are the only ones stable in solution but a number of crystalline compounds with Sj ions from n = 3 to n = 8 can be prepared, especially by using large cations (e.g., Cs+, NH4 and enH + and R3NH+). In all those with n = 4 to 8 the S—S distances run from 2.00 to 2.11 A and the S—S—S angles are ca. 110°. Structures of some S2" ions are shown in Fig. 12-3. 

ESR signals identical to those of the sulfuric solutions are recorded when hydrogen peroxide acts on phenothiazine in ethanolic solutions acidulated with HCl. ... 

Another type of analytical application of sulfuric acid oxidation has been developed recently, based on the intense fluorescence which appears when the sulfuric solutions containing oxidized pheno-thiazine derivatives are diluted with dimethyl sulfoxide. It has been shown that concentrations as low as 0.01 /xg/ml may be detected this way and that substituents in position 2 decrease the intensity of the fluorescence to a greater extent than side chains at position 10.1 1... 

For Rayleigh scattering / = 0 at 90°. As R increases, theory shows that X is a periodic function of diameter for monosize particles, and this has been used to measure particle size [78] specifically the size of aerosols in the size range 0.1 to 0.4 pm [79]. It has also been used to determine the sizes of sulfur solutions [80] In this work, transmission and polarization methods yielded results in accord with high order Tyndall spectra (HOTS) for sizes in the range 0.365 to 0.62 pm. In the limited region where (0.45[Pg.537]

HOTS have been studied extensively in monodisperse sulfur solutions by La Mer et.al. [98-101], by Kenyon [102], in aerosols by Sinclair and La Mer [103], in polystyrene latices by La Mer and Plessner [105] and in butadiene latices by Maron and Elder [106]. The following equations derived by Maron and Elder for the angular positions of the first red and green order, and are particular examples of equation (10.22).
