  • Process for the preparation of alkylhalosilanes
    Patent number: 5880307
    Abstract: A process for the use of water granulated silicon in the preparation of alkylhalosilanes. The process comprises contacting an alkyl halide described by formula RX, with a particulate water granulated silicon containing greater than 0.5 to about 5.0 weight percent iron, in the presence of a catalyst composition comprising copper, at a temperature within a range of about 250.degree. C. to 350.degree. C. where R is selected from the group consisting of alkyls comprising one to about four carbon atoms and X is a halogen.

  • Method of direct process performance improvement via control of silicon manufacture
    Patent number: 5059343
    Abstract: This invention discloses a method of treating silicon with non-volatile, phosphorous compounds to allow the silicon to be used in the direct process for the manufacture of alkylhalosilanes. The treatment of the silicon is carried out by feeding phosphorous compounds to the silicon during or after refining.

  • Method of direct process performance improvement via control of silicon manufacture
    Patent number: 4898960
    Abstract: What is disclosed is a method of improving the performance of the direct process for preparing alkylhalosilanes using an alkylhalide and silicon. The method is based on the control of the phosphorous that enters the silicon used in the direct process, by controlling the amount of phosphorous that enters the silicon during the manufacture of the silicon itself.

  • Method for preparation of alkylhalosilanes
    Patent number: 4762940
    Abstract: What is disclosed is a method for controlling a process for the preparation of alkylhalosilanes from silicon and alkyl halides where metal arsenides and alloys of arsenic are used as promoters to enhance selectivity, overall yields of usable silanes, and silicon utilization. Also, disclosed is a composition comprising a direct reaction silicon/copper contact mass which includes arsenic as a component.

  • Method of manufacturing alkylhalosilanes
    Patent number: 4602101
    Abstract: What is disclosed is a method of controlling a process for the preparation of alkylhalosilanes from silicon and alkylhalides where phosphorous or certain phosphorous compounds are used as promoters to enhance selectivity, overall yields of useable silanes and enhanced silicon metal conversion.
