    摘要: Aminated, alkoxylated hydroxyl-terminated polymers are made by a process involving first polymerizing one or more unsaturated hydrocarbons, such as butadiene, to form a liquid polymer. Next, the liquid polymer is provided with terminal hydroxyl groups. Then, the hydroxylated liquid polymer is alkoxylated with one or more alkylene oxides, such as ethylene oxide, propylene oxide, butylene oxide, and mixtures thereof, to provide secondary terminal hydroxyl groups. Finally, the alkoxylated liquid polymer is aminated over a transition metal oxide catalyst, such as a combination of nickel oxide/copper oxide/chromium oxide. If the alkoxylated, hydroxyl-terminated liquid polymer is terminated with primary hydroxyl groups, then the amination does not proceed well.

    摘要: A novel class of aromatic polyester polycarbonates is described. The polycarbonates are made by reacting an alkylene carbonate with an aromatic polyester polyol over a polycarbonate formation catalyst such as potassium stannate. In turn, the polyol is made by esterifying a dibasic acid waste stream with an alkylene glycol to produce a polyester polyol which is subsequently used to transesterify recycled polyethylene terephthalate.

    摘要: Economical, open-celled packaging foams of better quality than foams from commercial aromatic polyester polyols may be prepared with a novel polyol blend. The most important component in the polyol blend is an aromatic polyester polyol made from dibasic acid waste streams and recycled polyethylene terephthalate. This type of polyol made from waste or recycled reactant streams is economical to make and serves as an inexpensive substitute for a portion of more expensive amino polyols normally used.

    摘要: It has been surprisingly discovered in accordance with the present invention that when 1,3-dioxolane is reacted with formaldehyde in the presence of an organic peroxide and an ionizable, at least sparingly soluble metal salt, the reaction preferentially involves an addition of the formaldehyde to the 2-methylene group of the 1,3-dioxolane with only minor reaction with the 4-methylene and 5-methylene groups of the 1,3-dioxolane whereby the reaction product that is formed contains significant quantities of 2-hydroxyalkyl-1,3-dioxolanes. 2-Hydroxyalkyl-1,3-dioxolanes are hydrolyzed with comparative ease to ethylene glycol and the corresponding glycol aldehyde (CHO--CH.sub.2 --OH). The glycol aldehyde in turn can be catalytically hydrogenated to form additional quantities of ethylene glycol.

    摘要: An improved process for selectively preparing an N-(aminoalkyl)piperazine compound is disclosed wherein piperazine is contacted with a primary or secondary amino alkanol compound in the presence of a catalytically effective amount of a phosphorus-containing substance at a temperature of from about 250.degree. to about 350.degree. C under a pressure sufficient to maintain the mixture essentially in liquid phase and the N-(aminoalkyl)piperazine is then recovered from the resultant reaction mixture. In a preferred embodiment piperazine is contacted with monoethanolamine to produce N-(2-aminoethyl)-piperazine.
