摘要:A cw CO2 tunable laser is employed to irradiate an allyl halide selected from allyl chloride, allyl bromide, allyl fluoride, 2-methyl-3-chloropropene, and 2,3-dichloropropene and contained in one or more reaction cells at a predetermined pressure. A predetermined power level from about 25 to 150 watts, an irradiating time from about 0.2 second to about 60 seconds, and a selected radiation line for example P(36), P(32), P(28), P(26), or P(22) (that is resonant with an absorption band of the selected allyl halide) are employed to achieve dissociation of the selected allyl halide and to achieve a laser-induced photochemical synthesis of benzene and substituted benzenes.

标题 :Synthesis of cadmium sulfide using the laser-induced reaction of dialkylcadmium and organosulfur compounds
摘要:Cadmium sulfide is formed successfully from the laser-induced chemical reion between a first reactant of a dialkylcadmium and a second reactant of a dialkylsulfide. Infrared laser radiation in the range of 10.4 or 9.4 micrometers is provided by a continuous-wave CO 2 laser. In single line operation, output powers between 10 and 150 watts/centimeters square (W/cm 2 ) are obtained by variation of the CO 2 -N 2 -He gas mixture in the laser. The process procedure and sample handling is accomplished using standard vacuum line techniques. The irradiation of dimethylsulfide at R(18) of (00°1-10°0) for 5 seconds at 100 W/cm 2 produced the products methane, ethane, and sulfur. A mixture of a dialkylsulfide (CH 3 ) 2 S, and a dialkylcadmium (CH 3 ) 2 Cd is irradiated at R(18) of (00°1-10°0), 979 cm -1 for a total of 5 seconds at 100 W/cm 2 to form CdS on the windows of the reaction cell. A higher yield of CdS is obtained when the sensitizer SR 6 is added to the mixture of the reactants. Excitation of the mixture occurs using P(20) of (00°1-10° 0) at 944 cm -1 for 5 seconds at 100 W/cm 2 . The representative torr pressures of the reactants are for (CH 3 ) 2 Cd 33 torr combined with (CH 3 ) 2 S to total 100 torr pressure prior to irradiation. The efficiency when SF 6 (6 torr) plus (CH 3 ) 2 Cd (22.4 torr) is combined with 54.5 torr of (CH 3 ) 2 S and irradiated is improved.

标题:Synthesis of cadmium sulfide using the spontaneous reaction of dialkylcadmium and hydrogen sulfide
摘要:Cadmium sulfide is formed successfully from the reactants hydrogen sulfidemd the representative dialkylcadmium, dimethylcadmium, spontaneously when mixed in the gas phase. Reactions are monitored using fourier transform infrared spectroscopy which also permits the identification of gaseous products. The gaseous products of this reaction are identified as methane and ethene. The stoichiometry of the cadmium sulfide depends upon the reactant pressure ratios. The process procedure and sample handling is accomplished using standard vacuum line techniques. This particular process is extremely useful, as the stoichiometry of the product cadmium sulfide can be controlled by the purity of the starting materials and the ratios of reactant pressures. Typical reaction mixtures range from about 14 to 32 torr of dimethylcadmium and from about 30 to about 279 torr of hydrogen sulfide. The cadmium sulfide is formed as a reddish orange powder which is used as a precursor for a single crystal production for detector use.
