Method for the production of chorionic gonadotropin (CG) with properties similar to those of human CG (HCG) from a microorganism or mutant thereof isolated by natural or hybridization procedure from the body or body extract carrier of a malignant tumor carrier and having the capacity to synthesize the polypeptide hormone known as human chorionic gonadotropin in its total form or in its sub-units (.alpha. & .beta.) which comprises: (a) culturing the microorganism or mutant thereof in a culture me...

The present invention provides an improved process for the preparation of Dolasetron salts, in particularly Dolasetron mesylate. Also provided are intermediates for the process and methods of preparing the intermediates.

A process for producing a ferronickel product from a mixed nickel iron hydroxide product, said process including the steps of: providing a mixed nickel iron hydroxide product; pelletising the mixed nickel iron hydroxide product to produce nickel iron hydroxide pellets; calcining the nickel iron hydroxide pellets to produce mixed nickel iron oxide pellets; and reducing the nickel iron oxide pellets with one or more reducing gases at high temperatures to produce ferronickel pellets.

Production of aluminum by continuous electrolysis of aluminum chloride in molten electrolyte of controlled oxide content.

Production of phosphorus by reaction of a mixture comprising calcium phosphate, quartz sand and coke. The reaction is effected at 1,300.degree. to 1,700.degree. C by electrical heating in an autogenous bed of fluidized coke. The coke is used in particles with a size of 0.1 to 5 mm, and each of the calcium phosphate, quartz sand and coke components forming the mixture is used in particles with a size of 0.01 to 5 mm. The reduction furnace used in carrying out this process is comprised of a carbon...

A process for manufacturing high pressure, high purity hydrogen which comprises (a) generating at a pressure below about 450 psig a hydrogen-rich gas containing sufficient Co.sub.2 so that the molecular weight of the hydrogen-rich gas is at least four; (b) centrifugally compressing the hydrogen-rich gas from a pressure below about 450 psig to a substantially higher pressure above 450 psig to obtain high pressure hydrogen-rich gas; (c) removing CO.sub.2 from the high pressure hydrogen-rich gas to...

Process for the production of a methane-rich gas stream from a hydrocarbonaceous feedstock with all steps being carried out at or slightly above the desired pressure of delivery. Effluent gas from a free-flow partial-oxidation synthesis-gas generator, and preferably containing from about 10-26 volume percent methane on a dry basis is reacted with steam and without a catalyst at a temperature in the range of 2,800 to 1,500.degree. F. to produce a stream of shifted gases having a mole ratio H.sub....

Benzene is efficiently recovered and the alkylating process is made to run more efficiently to produce ethylbenzene in the process of alkylating benzene with dilute ethylene by recirculating a large volume of polyethylbenzene to efficiently recover the benzene in the off-gases, splitting the benzene-rich polyethylbenzene scrubber effluent, returning a small approximate reaction equilibrium quantity of polyethylbenzene to the reactor, and then processing both the remaining benzene-rich scrubber e...

Production of pure acetylene from a cracked gas obtained by cracking gaseous hydrocarbons, the process comprising a number of steps wherein the higher C.sub.3 to C.sub.5 hydrocarbons remaining in the crude acetylene are washed out with an organic solvent such as toluene.

Production of alkenediols from alkenols in which the hydroxyl group is in the .beta.-position to, or is farther removed from, the double bond and which bear at least one hydrogen atom on at least one carbon atom adjacent to the carbon atoms of the double bond, by reaction with an aldehyde at from 235.degree. to 400.degree.C.
