Orange origin

Diarylide Yellows and Oranges. Originally called benzidine yellow and orange, this family has six derivations AAA, AAOA, AAOT, AAMX, and HR [1],... 

Secondary Disazo Dyes. There are about 250 dyes of known constitutions in this group. They are made by diazotizing an aminoazo compound, the amino group of which derives from the original coupling component and coupling it to a suitable intermediate. Intrasil Orange YBLH... 

California contains the largest formation of diatomite in the United States the Monterey Formation extends from Point Arena in Mendocino County in the north to San Onofre in the south (7). The most extensive deposit is near Lompoc, Santa Barbara County, and is of marine origin. A freshwater deposit is being mined near Burney, Shasta County. Other important deposits (not mined as of this writing) are located in Monterey, Fresno, Inyo, Kem, Orange, San Bemadino, San Joaquin, Sonoma, and San Luis Obispo counties. 

Figure 2.20 Austenitic stainless steel plate from plate-and-frame heat exchanger. The orange oxide was formed from corrosion product originating at the regularly spaced pits. Pits are present near points of contact between adjacent plates. Corrugations run at right angles on adjacent plates.

At pH 7, [H ] = [OH ] that is, there is no excess acidity or basicity. The point of neutrality is at pH 7, and solutions having a pH of 7 are said to be at neutral pH. The pH values of various fluids of biological origin or relevance are given in Table 2.3. Because the pH scale is a logarithmic scale, two solutions whose pH values differ by one pH unit have a 10-fold difference in [H ]. For example, grapefruit juice at pH 3.2 contains more than 12 times as much H as orange juice at pH 4.3. 

Although the orange-yellow solid prepared by Bartlett (p. 892) was originally formulated as Xe+[PtF6] , it was subsequently found to have the variable composition XefPtFe), x lying between 1 and 2. The material has still not been fully characterized but probably contains both [XeF]+[PtF6] and [XeF]+[Pt2Fi,]-. 

In all the foregoing cases, the percentage of aldehyde or ketone is so high that the estimation by the above processes can be sufficiently accurately carried out on the original oil. With such oils as lemon, orange, hand-pressed lime, and citron or cedrat, however, the proportion of aldehydes is so small that it is not possible to satisfactorily determine it directly on the oil itself by absorption processes, and a preliminary concentration of the aldehydes in the oils by carefully fractionating out the hydrocarbons in vacuo has therefore been proposed by Burgess and Child who recommend the operation to be carried out as follows —...

Annatto is a colored pigment that is extracted from the Central and South American plant Bixa orellana. The color comes from the resinous outer covering of the seeds of the plant, which is composed of the carotenoid pigments bixin and norbixin and their esters. The central portion of those molecules is the same as that of the molecule beta-carotene, and the yellow-orange color of annatto comes from the same physical chemistry origins as the orange color of beta-carotene. 

S7O crystallizes in orange monochnic crystals which are yellow at —80 °C and melt with decomposition at 55 °C. However, even at 25 °C S7O decomposes quantitatively within 24 h in diffuse daylight, more slowly in the dark, to SO2, polymeric sulfur and httle Sg. Thermolysis in a high vacuum at 60 °C produces S2O and elemental sulfur. Therefore, the El mass spectrum exhibits only ions originating from these decomposition products (SO, 830, S ). In CH2CI2 solution S7O decomposes at 20 °C within 3 h to SO2, polymeric sulfur and Sio the latter can be isolated in 7% yield based on the starting material 87 [62] ... 

Color is a spectacular property of coordination complexes. For example, the hexaaqua cations of 3 transition metals display colors ranging from orange through violet (see photo at right). The origin of these colors lies in the d orbital energy differences and can be understood using crystal field theory.
