A method is provided for making alkylhalosilanes by effecting reaction between an alkyl halide, such as methyl chloride and powdered silicon in the presence of a copper-zinc-tin catalyst. Significant improvements in reaction rate and product selectivity are achieved when copper is employed at a critical weight percent relative to silicon and critical weight ratios of tin and zinc are employed relative to copper.

An improved process for the continuous separation of a thermoplastic resin from solutions thereof in organic solvents.

Process for recovery of solid thermoplastic resins from solutions

An improved process for the continuous recovery of solid thermoplastic resin from organic solvent solutions using a modified slurry granulation-steam stripping process.

Bisphenol-A waste stream derived from the reaction of phenol and acetone in the presence of an acidic condensing agent can be treated with a molecular sieve to obtain good yields of phenol present in the effluent stream either in isolated form or as part of the compounds present in the waste stream.

Phenol recovery from bisphenol-A waste streams

A vapor compression cycle device is described which includes a multi-component working fluid mixture, and an improved condensing heat exchanger. The vapor compression cycle device includes also a high-pressure liquid accumulator with an associated flow restricting device positioned between the condensing heat exchanger and the evaporating heat exchanger, and a liquid accumulator positioned between the evaporating heat exchanger and the compressor. A method is also described of modulating the capacity of such a device.

Vapor compression cycle device with multi-component working fluid

A vapor compression cycle device is described which includes a multi-component working fluid mixture, a high-pressure liquid accumulator with an associated flow restricting device positioned between the condensing heat exchanger and the evaporating heat exchanger, and a low-pressure liquid accumulator positioned between the evaporating heat exchanger and the compressor. A method is also described of modulating the capacity of such a device.
