Green Papers

Sulphur dioxide is evolved (odour of burning sulphur turns potassium dichromate paper green decolourizes fuchsin solution). 

Atropine Paper. Green tissue paper imbued with a solutiou of sulphate of atropia, so that a piece onc-fiflb of an inch square contains as much as a drop of a solution 2 grains to 1 ounce of water. The paper is hung up and turned about while drying. A pieco of tlio size named will dilate the pupil if placed on tho sclerotic, and tho lids dosed over it and tied with a handkerchief. 

Congratulations Osvaldo It is a pleasure to contribute this paper to a special volume in honour of Osvaldo Goscinski. The senior author has known Osvaldo since he began his graduate work in the Florida, Quantum Theory Project, shortly after Osvaldo had finished his dissertation and moved to Uppsala. His paper Greens functions approach to IPs and his inner projected super-operator formulation of Greens functions are routinely used by us and many others today. 

Vapors from natural rubber (NR) produce a deep blue or blue-violet color, and those from styrene-butadiene rubber (SBR) pyrolysis turn the paper green or blue with a distinct green tinge. Polyisobutylenes and butyl rubber resemble NR, and silicone rubbers resemble SBR, in this color reaction. Pyrolytic vapors from nitrile rubbers, on the other hand, give a brown or brown-yellow color and those from polychloroprenes (neoprene) turn the test paper grey with a yellow tinge.

A theoretical study by Green and Jardine suggests that the elimination of CH4 proceeds through an ri -H,H o complex. In a later paper. Green et al. examined the theoretical aspects of analogous W and Mo systems and the consequences of the fact that the M(Cp>2 species have triplet electronic ground states. 

Neutralization The solution on the left turns pH paper red because It is acidic. The solution on the right turns pH paper blue because it is basic. When equal numbers of Hg0+ and 0H from tbe acidic and basic solutions react, the resulting solution is neutral. The neutral solution turns pH paper green. 

This reaction is a useful test for a sulphite or for moist sulphur dioxide, which turns dichromate paper (filter paper soaked in potassium dichromate) from yellow to green. 

Thus, filler paper which has been dipped into a solution of potassium dichromate turns green in the presence of sulphur dioxide. This reaction provides the usual test for sulphur dioxide. 

Oxidation, (i) Dissolve 5 g. of potassium dichromate in 20 ml. of dil. H2SO4 in a 100 ml. bolt-head flask. Cool and add 1 ml. of methanol. Fit the flask with a reflux water-condenser and warm gently a vigorous reaction soon occurs and the solution turns green. The characteristic pungent odour of formaldehyde is usually detected at this stage. Continue to heat for 3 minutes and then fit the flask with a knee-tube (Fig. 59, p. 100) and distil off a few ml. Test the distillate with blue litmus-paper to show that it is definitely acid. Then apply Test 3 p. 350) for formic acid. (The reflux-distillation apparatus (Fig. 38, p. 63) can conveniently be used for this test.)...

Statistics for the production of basic dyes include those products hsted as cationic dyes, eg, cyanines, for dyeing polyacrylonitrile fibers and the classical triaryhnethane dyes, eg, malachite green, for coloring paper and other office apphcations (2,53). Moreover, statistics for triaryhnethane dyes are also hidden in the production figures for acid, solvent, mordant, and food dyes, and also organic pigments. Between 1975 and 1984, the aimual production of basic dyes in the United States varied from 5000—7700 t. However, from 1985—1990, aimual production of basic dyes varied from 5000—5700 t, and the annual sales value increased from 56 to 73 million per year.
