Carius (8) replaced the oxygen in phosphoryl chloride by sulfur. This may be somewhat analogous to the replacement of oxygen in a carbonyl group by sulfur using phosphorus pentasulfide. Prinz (8) used thionyl chloride in his reaction with phosphorus sulfide and De Fazi (2) used carbon tetrachloride in a very interesting preparation of this important intermediate. 

The correlation between the heat offormation AHf and the work function WF. Table 5.11 is showing the heat of formation of AHf of the oxides, sulfides, chlorides and phosphorus compounds and the average work function (WF) of the elements. The work function is a complicated physical property related to the crystal orientation, surface composition, and chemisorption (Shpenkov, 1995). Taking an aluminum surface as an example (Huber and Kirk, 1966), the adsorption of dry oxygen to one monolayer coverage will lower the work function by 0.05... 

Compound typically containing sulfur, chlorine, or phosphorus lubricant which reacts with surface of the metal or tool to form a sulfide, chloride, or phosphide compound which has a low shear strength. 

Several procedures have been reported for the synthesis of phosphorus (V) sulfochloride. These include the reaction of phosphorus(V) chloride with hydrogen sulfide,1,2 of phosphorus (III) chloride with sulfur,3 4 of carbon tetrachloride with phosphorus(V) sulfide,5 and of phosphorus(V) chloride with phosphorus(V) sulfide.5 The second and fourth methods form the bases for the two syntheses presented here. 

Preparation from Phosphorus (V) Sulfide and Phosphorus (V) Chloride... 

The older literature reports the synthesis of phosphorus-(V) sulfochloride by reaction of phosphorus (V) chloride with phosphorus (V) sulfide in a sealed tube at 120°. Experience has shown that pressures as great as 700 p.s.i. may result under these conditions, indicating that an autoclave or bomb should be used. In the absence of these, the reactor shown in Fig. 8 is suitable. It consists of an oil bath containing a lecture bottle fitted with a pipe plug (iron pipe size, % in.), a thermometer, and a knife type of immersion heater. Although no difficulty has been experienced in the use of this reactor, it is well to keep it behind a barricade during the reaction. 

In a hood, 211 g. of powdered phosphorus(V) chloride (1.01 mols) is intimately mixed with 75 g. of powdered phosphorus ) sulfide (0.338 mol) in a 500-ml. beaker. This mixture is then transferred to the lecture bottle. Use of a 150-mm. short-stemmed funnel and a stirring rod facilitates this transfer and keeps the pipe threads clean. After treatment with pipe-joint compound, the pipe plug is screwed into place. (A satisfactory pipe-joint compound can be made by grinding litharge and glycerol together.)...
