    摘要: The present invention relates to the preparation of mixtures of sterically hindered substituted N-secondary amino acids or their alkali metal salts by a one-step reductive condensation of an amino acid or its alkali metal salt containing a primary amino group and a ketone to thereby form a mono-substituted amino acid or alkali metal salt thereof, followed by preparing the corresponding sterically hindered tertiary amino acids or alkali metal salt thereof by reacting the mono-substituted amino acids or alkali metal salt thereof with an unhindered aldehyde under reducing conditions in the presence of a hydrogenating catalyst. The novel mixtures of the sterically hindered mono-substituted amino acids and the tertiary amino acids and their alkali metal salts are useful promoters for alkaline salts in "hot pot" acid gas scrubbing processes.

    摘要: Acidic gases are substantially removed from a normally gaseous mixture by a process comprising contacting the normally gaseous mixture with an amine-solvent liquid absorbent comprising (i) an amine mixture comprised of at least about 50 mol % of a sterically hindered amine and at least about 10 mol % of a tertiary amino alcohol, wherein said sterically hindered amine contains at least one secondary amino group which is part of a ring and is attached to either a secondary or tertiary carbon atom or a primary amino group attached to a tertiary carbon atom, and (ii) a solvent for said amine mixture which is also a physical absorbent for said acidic gases. The liquid absorbent may also include up to about 35 weight percent water. The coaction of the sterically hindered amine and the tertiary amino alcohol in conjunction with the solvent provides an increase in the amount of CO.sub.2 containing acidic gases absorbed compared to the use of the same sterically hindered amines alone and lowers the heat of reaction.

    摘要: The instant invention relates to novel block copolymers containing olefin sulfur-dioxide segments and a process for their preparation. The olefin of choice is a "strained" olefin thus capable of reaction with SO.sub.2 in the presence of radicals at very high rates. Examples of strained olefins include cyclopropene, cyclobutene, norbornene, and the derivatives thereof. The novel block copolymers are prepared by contacting the olefin and the sulfur dioxide with a polymer under conditions of shearing degradation whereby said polymer is broken down into radical-containing segments which subsequently combine with the olefin and sulfur dioxide to form the novel copolymers described above. The polymer may be selected from the group consisting of polyisobutylene, poly(ethylene oxide), ethylene-propylene copolymers, poly(propylene oxide), polybutadiene, polyisoprene, etc. A novel block polymer formed by this preferred process shows improved properties as compared to physical mixtures of said polymer and olefin-sulfur dioxide copolymers. For example, the novel polymers formed by the preferred process of the instant invention show higher moduli and may be plasticized to higher levels while retaining good physical properties.
