Related reactions are those of sodium azide with carbon disulflde to give 5-mercapto-l,2,3,4-thiatriazole (see 8ection IV) and with thio-carbonyl chloride to give 5-chloro-l,2,3,4-thiatriazole. ... 

After refluxing, disconnect the trapping tube, and transfer the yellow solution into a 25-mL volumetric flask. Rinse the mbe with ethanol, and adjust the solution to volume with ethanol. Measure the absorbance of the solution at 435 nm against a blank prepared by diluting 15 mL of color reagent to 25 mL with ethanol. Determine the carbon disulflde content from a calibration curve obtained by plotting carbon disulfide concentrations of different standard solutions on the abscissa versus the absorbance on the ordinate. 

Hexafluoro-2-butyne and carbon disulflde react to give the tetrakis-(trifluoromethyl)tetrathiafulvalene quantitatively only in the presence of trifluoroacetic acid (70JA1412 73JA4379). The carbene initially formed is protonated the 1,3-dithiolium ion subsequently combines with the nucleophilic carbene to give the trifluoromethyl-substituted tetrathiafulvalene. 

Refluxing of two equivalents of aryliminophosphoranes 82 with carbon disulflde in benzene for two hours affords symmetrical diarylcarbodiimides 83 in excellent yields. The intermediate in this reaction is the corresponding isothiocyanate. ... 

The NMR spectra were obtained on a Bruker WP-60 at 15.08 MHz, with 3-sec delays, no decoupling, and typically 50,000 scans. The samples of chloroform-soluble product were made up to 50% (wt/vol) in deuterochloroform with carbon disulflde as an internal standard. The was determined from integration of the peaks in the aliphatic and aromatic regions. It was shown that lengthening the delay period did not result in larger /. ... 

Bis(trifluoromethyl)diazomethane is a reactive, electrophilic compound. It forms adducts with nucleophiles such as amines and phosphines and adds to olefins, acetylenes, and thiocarbonyl compounds to form heterocycles. It has been used as a source of bis(trifluoromethyl) carbene in reactions with benzene, saturated hydrocarbons, carbon disulfld< , and transition metal (iompounds, and it nndergoe.s a uni< im radicuil chain n aidion with saturat d hydrocarbons l.o form addiict.s that are hydrazonc.s and azines. ...

Caution Carbon disulflde fumes are poiaonous. Always cap an open container of carbon disulfide as soon as possible. Work in a well veutilafed area. 

Dimorphism.—Although most substances crystallize, if at all, in one simple form, or in some of its modifications, a few bodies are capable of assuming two crystalline forms, belonging to different systems. Such are said to be dimorphous. Thus, sulfur, as obtained by the evaporation of its solution in carbon disulfld, forms octahedra, belonging to the fourth system. Wlien obtained by cooling melted sulfur the crystals are... 

Chemical.—All forms of C combine with O at high temperatures, with light and heat. The product of the union is carbon dioxid if the supply of air or O be sufficient but it O be present in limited quantity, carbon monoxid is formed. The alflnity of C for O renders it a valuable reducing agent. Many metallic oxids are reduced, when heated with C, and steam is decomposed when passed over red-hot C HaO- -C=CO-i-H2. At elevated temperatures C also combines directly with S, to form carbon disulfld. With H, carbon also combines directly, under the influence of the voltaic arc. 

If the urine contain iodids or bromids, they must be removed, by acidulating the solution or the residue of incineration with HjS04, removing the iodin or bromin by shaking with carbon disulfld, neutralizing the aqueous solution w ith calcium carbonate and proceeding as above.
