Iron red

Note The dipping reagent, which can also be applied as a spray reagent, can be employed on cellulose and silica gel layers. A 3% solution of 2,2 -bipyridine in 40% thioglycolic acid can be employed as a specific spray reagent for the detection of iron (red coloration) [7],... 

Oxyd-rot, n. a kind of iron red Turkey red. -achicht,/, layer or film of oxide, -tiberzug, m. coating of oxide. 

Cobalt produces pale blue and iron red-brown chromatogram zones on a colorless background.

During roller-blending to disperse iron red pigment (iron(III) oxide) into plasticised cellulose nitrate, the mixture became a gel after 15 passes and tended to self-ignite. 

The separation of the elements from metals is a process in which you should provide yourself with good apparatus, and with experienced manipulation and workmanship. First make an aqua fortis thus take of alum, vitriol, sal-nitri, equal parts, distil to a strong aqua fortis, return that to the residue and distil a second time in a glass flask. Dissolve in this silver and afterwards dissolve in it sal ammoniac. After this is done take the metal in thin plates and dissolve it in the water. When that has taken place separate it in the water bath (balneo mar is), pour it over again until an oil is found at the bottom from gold almost brown, from silver almost bluish, from iron red to almost black, from mercury quite white, from lead lead-colored, from copper quite green, from tin, yellow.

Reducing agents (sulphur dioxide, solution of tin (II) chloride, iron (II) sulphate, hydroxylamine hydrochloride, hydrazine hydrochloride or hydriodic acid (KI+HCl), zinc or iron) red precipitate of selenium in hydrochloric acid solution. The precipitate frequently turns greyish-black on warming. When solutions in concentrated hydrochloric acid are boiled or evaporated, serious losses of selenium as SeCl4 occur.

From left to right, the compounds contain the following transition metals scandium (white), titanium (white), vanadium (light blue), chromium (yellow), manganese (light pink), iron (red-orange), cobalt (violet), nickel (green), copper (blue), and zinc (white). 

Remote sensing has the potential to detect hydrocarbon-induced alteration in rocks, soils and vegetation. Extensive studies have been performed on the reduction of ferric iron (red-bed bleaching), the conversion of feldspars and mixed-layer clays to kaolinite, the increase of carbonate content and the anomalous spectral reflectance of vegetation. 

The variables x, x2 and x3 in Figure 3.2 could for example represent measurements of iron, red color and red blood cell volume in the blood of patients (the objects). Because all the three variables are correlated, the straight line representation gives a sufficient summary of the data. The three-dimensional coordinate system may be exchanged with a new one-dimensional coordinate system where the new latent variable is a combination of the original three manifest (measured) variables. For a more complex chemical example, suppose chemical composition is measured in a number of lakes. Then the lakes are the I objects and the results of the chemical analyses (e.g., Cl-, NO ", SO4-, Na+, Fe2+, PO4-,... 

VOGEL S IRON RED (1309-37-1) Violent reactions with powdered aluminum (thermite reaction), hydrogen peroxide, calcium disilicide (thermite reaction), ethylene oxide (may cause explosive polymerization), calcium hypochlorite, hydrazine, hydrogen trisulfide, powdered magnesium. Incompatible with powdered calcium carbide, carbon monoxide, chlorides, guanidinium perchlorate, metal acetylides. Contact with the explosive hydrazinium diperchlorate or ammonium perchlorate can be made more heat-, shock-, or friction-sensitive. Incompatible with aluminum-magnesium-zinc alloys.
