Abstract: The use of fumed silica in a mixture of powdered silicon and cuprous chloride has been found to reduce agglomeration in a fluid bed reactor during the production of alkylhalosilane under continuous conditions.

Abstract: An improved direct process for producing organohalosilanes and particularly diorganodihalosilanes from silicon metal and an organohalide comprising contacting the two reactants in the presence of a partially oxidized copper catalyst having a surface area of at least 3.5 m.sup.2 /gm and wherein 100% of the particles are less than 35 microns in size and wherein 100% of the particles are over 0.7 microns in size.

Abstract: An apparatus is disclosed for obtaining from a fluid stream, a sample having a volume that is proportional to the flow rate of the fluid stream. The apparatus comprises intake means for withdrawing fluid material from a stream; a sampling reservoir having a conduit inlet at the top and an outlet at the bottom; an equalizer chamber in communication with said sampling reservoir, said equalizer chamber being operated in conjunction with a gas bubbling system to maintain the level of liquid in said sampling reservoir so that the volume of said liquid is proportional to the flow rate in said fluid stream.
