  • Patent number: 4879401
    Abstract: A process is provided for removing impurities from the gaseous product of an alkyl nitrite production zone by contacting a portion of it with lower alcohol and oxygen to convert substantially all of the nitric oxide in that portion of the gaseous product stream to alkyl nitrite, the oxygen being present in an amount such that the mole ratio of nitric oxide to oxygen is in the range of about 4:1 to about 2:1 and the lower alcohol being present in the reaction zone such that the mole ratio of nitric oxide to lower alcohol is about 1:1 or less. A recovery stream, comprising alkyl nitrite substantially free of nitric oxide, is withdrawn from the reaction zone and at least a portion of the alkyl produced in the reaction zone is removed. A least a portion of the balance of the recovery stream from which the alkyl nitrite has been removed is purged, thereby removing impurities from the process.

  • Patent number: 4877886
    Abstract: Cyclic alkylene carbonates are produced by the homogeneous catalytic reaction of alkylene oxides with carbon dioxide during which process, polyglycols are formed. The catalyst is separated by distallation from the alkylene carbonate and is recycled to the reaction while associated with polyglycols. A purge stream is removed from the recycle to prevent an undue concentration of polyglycols in the reaction and catalyst is separated from the purge stream by acylation of the polyglycols enabling precipitation of the catalyst.

  • Patent number: 4873042
    Abstract: A process for extruding a hydrolyzable particulate thermolastic copolymer coated with an organic peroxide, which, under extrusion conditions, will provide essentially no crosslinking per se, but will decompose to provide a silanol condensation catalyst, including passing the coated copolymer through an extruder having a die at about its downstream end with the proviso that the extruder is operated under such conditions that (i) the temperature of the extruder before the die is maintained at a level sufficient to extrude the copolymer, but below the decomposition temperature of the organic peroxide; (ii) the temperature of the extruder at or after the die is maintained at or above the decomposition temperature of the peroxide; and (iii) there is sufficient moisture in the environment to crosslink the copolymer in the presence of a silanol condensation catalyst.
