In the presence of a heavy-metal chloride and water at 80—240°C, and under sufficient pressure to maintain the water ia the Hquid phase, diethyl ether reacts with hydrochloric acid to give ethyl chloride (37). 

Sutin et al have made a detailed study of the chloride-catalysed paths in deuterated water media, the exchange occurring more slowly in this solvent than in water. Accurate values of, in both water and heavy water, were obtained by spectrophotometry and enabled more precise rate parameters to be calculated. For aqueous media, values are 22.8 l.mole sec fork (n = 0.50 Af and 20 °C),...

Deuterated C60 C60D36 was synthesized in n-hexane using the same procedure detailed above for C60H36 using Zn dust and 37% deuterium chloride (DC1) in heavy water (D20). After complete reduction also the electronic absorption spectrum of C60D36 is dominated by a maximum at 217 nm and the molar extinction coefficient was determined e217 = 16480 L cm-1 mol-1. 

C70D38 was synthesized in n-hexane using the same procedure detailed above for C70H38 using Zn dust and 37% deuterium chloride (DC1) in heavy water (D20). 

Preparation of DCI. If DCI gas is not available in a commercial cylinder or bulb, it must be prepared in the laboratory. Deuterinm chloride gas can be synthesized readily by the reaction between benzoyl chloride and heavy water ... 

Heavy water (2.5 mL at least 95 percent D2O) benzoyl chloride (70 g) ice or Dry Ice and isopropanol liquid nitrogen or a 5-L flask of DCl gas (available from Cambridge Isotope Laboratories, 20 Commerce Way, Woburn, MA 01801, and other suppliers of iso-topically substituted compounds). 

The pathway by which the hydrogen chloride inhibits the telomerization and thus produces mono-ethylcyclohexane was supported by use of a solution of deuterium chloride (38%) in heavy water (99% deuterium oxide) as promoter under the standard conditions. The reaction mixture included 1.15 mols of cyclohexane and... 

Calculations showed that the amount of deuterium in the cyclohexane, ethylcyclohexane and other hydrocarbons was actually more than that present in the deuterium chloride charged. Hence, it was concluded that the deuterium present in the deuterium oxide also underwent exchange. This was confirmed by analysis of the recovered acid solution. Its mass spectrum showed that most of the D2O was converted into DOH and H2O. Exchange of the proton of hydrogen chloride with deuterium of the "heavy water" occurred via formation of a hydrated proton, (H-OD2) in which the hydrogen and deuteriums are indistinguishable.

Many methods have been used to determine the deuterium content of hydrogen gas or water. For H2/D2 mixtures mass spectroscopy and thermal conductivity can be used together with gas chromatography (alumina activated with manganese chloride at 77 K). For heavy water the deuterium content can be determined by density measurements, refractive index change, or infrared spectroscopy.
