The kinetic spectra of Aurine, Indanthrene Yellow, and Golden-Orange are similar to those of Chlorophyll. 

Color. Many US Military Specifications for expls and materials used in their manuf have color requirements. For example AN, Amm Chlorate, Amm Perchlorate, EDD, EDNA, HMTeA, LA, PE, PETN RDX should be white DNB Sc DNT pale yellow DNPh, HNDPhA, MNN, PA, TNAns TNB yellow AmmP golden orange and TNT light tan (buff) Because of this, it is appropriate to list here, some references on color, color designation and color measurements Refs l)Thorpe 3 (1939), 295-306 2)A.H. 

To a solution of 6.7 g 2,5-dimethoxy-(i-propylthio)benzaldehyde in 40 g of nitromethane there was added 0.10 g of anhydrous ammonium acetate, and the mixture was heated on the steam bath for 2 h. The excess reagcnt/solvent was removed under vacuum yielding 8.9 g of orange solids. This was recrystallized from 200 mL boiling MeOH providing 6.2 g of 2,5-dimethoxy-B-nitro-4-(i-propyT thio)styrene as lustrous golden orange platelets.

Phenylazo)phenyl Tellurium Acetate1 A solution of 0.082 g (1 mmol) of sodium acetate in 20 ml dry methanol is added under an atmosphere of nitrogen to a stirred solution of 2-(phenylazo)phenyl tellurium chloride (0.344 g, 1 mmol) in 25 ml dichloromcthanc at 20°. The mixture is stirred for 20 min and the solvents removed on a rotary evaporator. 100 ml dichloromethane are added to the residue. The mixture is stirred vigorously and then filtered to remove insoluble sodium chloride The solvent is removed from the filtrate on a rotary evaporator. 5 ml methanol are added to the residue, the mixture is stirred well, and then filtered to collect the product. The crude material is dissolved in petroleum ether (60-80°). Slow evaporation of the solvent caused golden-orange crystals to form yield 75% ,fn.p. 121-122° (dec.).

The sodium potassium tartrate initially forms the soluble blue copper(II) tartrate complex witli the copper sulfate the color of this complex is a deeper blue than that of the hydrated ion. At the temperature of the experiment reduction to the beautiful golden orange CuzO occurs, and at the same time oxygen and (rather less) CO2 are formed in the redox proce.ss these are responsible lor the foaming of the solution. This reversible color reaction can be repeated several times when further hydrogen peroxide is added. The pH of the system increases from 5 to about 9. ... 

A further development was the fusion of 2 methyl anthraquinone with caustic alkali, when water was eliminated, and the dyestuff Indanthren Golden Orange G (C.I. vat orange 9), (21), containing the characteristic pyrene structure, (20), was the resultant product. 

RuH(C5H5)(C8H,2) is prepared from [RuH(C8H,2)(NH NMe2)3]PF6 by the published procedure [217]. To a pentane (150 mL) solution of RuH(C5H5)(CgH,2) (5.51 g, 20.0 mmol) is added carbon tetrachloride (2 mL). The reaction mixture is stirred at room temperature for 5 min to give golden orange microcrystals. The microcrystals are collected by filtration and dried under vacuum. Yield 5.1 g, (82 Yo). 

Chiyeopbanic acid crystallizes in golden, orange-yellow, interlaced ueedlea it is almost tasteless and odorless fuses at 162 (291.
