Silicon of high purity is used in making semiconductor devices. Silicon for this purpose is made by decomposing silane in a fluidized bed reactor. This process entails thermal decomposition of silane to deposit additional metallic silicon on particles of high purity silicon. To obtain good process economics, two modes of operation are used. In a first mode, the reactor is operated under high productivity conditions which also result in co-production of silicon dust or fines. Some of the dust is deposited on the product silicon particles and some of it is elutriated by gas flow in the reactor and removed through an exit point near the top of the reactor apparatus. The dust on the particles can cause problems in handling. For example, in bagging the particles, or removing the particles from a bag, the dust can become airborne from the larger particle surfaces and form an objectionable cloud of silicon dust. The invention provides a method for uniting dust to the larger silicon particles, and also provides the improved silicon particles produced by the process.

Linear 1-olefins are continuously prepared from internal olefins by (i) continuously feeding internal olefin, isomerization catalyst and tri-lower alkyl aluminum to a reaction zone so as to cause the internal olefin to isomerize to 1-olefins which displace the lower alkyl groups to form a trialkyl aluminum compound in which at least one of the alkyl groups is a linear alkyl derived from the 1-olefin, (ii) continuously removing trialkylaluminum compound from the reaction zone and, thereafter (iii) reacting the trialkyl aluminum compound with a 1-olefin so as to displace the linear alkyl from the trialkyl aluminum compound, thereby forming a linear 1-olefin product which is substantially free of internal olefins.

Novel and very useful forms of sodium (S)-2-(6-methoxy-2-naphthyl)propionate are provided. These forms are sodium (S)-2-(6-methoxy-2-naphthyl)propionate monohydrate having an average particle size significantly larger than about 70 microns--the size of conventional sodium (S)-2-(6-methoxy-2-naphthyl)propionate--and a chiral purity of at least 98% (S)-enantiomer. Process technology enabling the production of such novel products is also described. The provision of such novel products makes possible significant improvements in processing time, plant capacity and product handling operations.

Particles of silicon and a p or n carrier substance which are in spherical or spheroidal form, and suitable for use in the preparation of doped semiconductor devices, can be prepared by a fluidized bed technique for chemical vapor deposition of a carrier substance (B, P, As or Sb). The prepared products have a kernel of high purity polysilicon and a layer of silicon/dopant alloy upon the kernel. Optionally, the particles have a thin outer layer of silicon.

The alpha-olefin content of mixed hydrocarbon streams is selectively utilized to produce trialkylaluminum compounds in which the alkyl groups are linear primary alkyl groups. This selective utilization is accomplished by use of a specific, highly selective low residence-time, low isomerization catalytic displacement reaction. In addition, when alpha-olefins are the desired end product, a second low residence-time catalytic displacement reaction is utilized whereby high purity alpha olefins are produced.
