Methyl chloride calculated pressures

Example 3.7 Given that the vapor pressure of methyl chloride at 60°C is 13.76 bar, use the Redlich/Kwong equation to calculate the molar volumes of saturated vapor and saturated liquid at these conditions. 

To a clean dry test tube at the desired temperature, calculated amounts of methyl chloride, 2,4,4-trimethyl-1 -pentene, n-nonane and the alkylaluminum compound were added and the test tube was stoppered with a rubber septum cap. The content of the test tube was mixed by shaking and the calculated amount of f-butyl chloride in methyl chloride solvent was rapidly added with a syringe. After 25 min the reaction was terminated by slow addition of prechilled methanol. During termination the septum cap was removed to prevent pressure build-up due to the formation of gaseous products. The tube was removed from the drybox and the solvent was slowly evaporated. To facilitate the separation of the organic products from the aluminum oxide residues a saturated aqueous sodium-potassium tartrate solution was slowly added at 0° C. On adding excess water, the aluminum oxide-tartrate complex can be dissolved to yield well separated aqueous and organic layers. The... 

Let us now suppose that we are asked to calculate the thermal energy required to heat a sample of methyl chloride (at constant pressure) over a range of temperature, say from 7 to 7 2. From the definition of (... 

Carnahan and Starling (14) have used the VDW equation to calculate the equation of state of methyl chloride, whose critical constants (15) are listed in Table II. Their results are given in Table III. As expected, the VDW equation grossly overestimates the pressure.

Shiflett and co-workers coated thin uniform layers of PFA (Dija laboratories) to porous stainless steel tubes by ultrasonic deposition and carbonized at 723 K to form crack-free supported nonporous carbon (NPC) membranes [10]. Methyl chloride porometry was performed with variation in both pressure and temperatwe. Figure 6.27 shows the results of the measurement and calculation. Applying Hor-... 

Synthesis. The copolymers were prepared by suspension polymerization using a 1 gal stainless steel reactor operating at the autogenous pressure of vinyl chloride at 50° C. The vinyl chloride (Matheson) was purified by passing the gas over KOH pellets. A 9 1 ratio of water to vinyl chloride was used, the suspending agent being methyl cellulose (Methocel 25 cps, Dow Chemical). Percadox 16 (Noury Chemical Corp.) was the catalyst. Because the calculated reactivity ratios indicated that...
