Abstract: Alkyl-substituted bicycloalkyl ether compositions useful in the preparation of synthetic lubricant compositions are obtained by reacting an alkyl-substituted 2-norbornene with a monohydric alcohol in the presence of an acidic catalyst.

Abstract: Methacrylamidopropyltrimethylammonium chloride or its free amine, dimethylaminopropylmethacrylamide, is purified by contacting aqueous solutions of the salt or the free amine with solid, nonionic organic resins. Such resins absorb the organic impurities, yet leave behind the polymerization inhibitor.

Abstract: The corrosion of iron and steel surfaces by an aqueous alkanolamine conditioning solution used to remove CO.sub.2 from a gas stream is effectively inhibited by a combination of a vanadium containing ion and a di- or triamine. A surprising fact is that some of the amine co-inhibitors have been identified by others in the art as promoting ferrous metal corrosion.

Abstract: The corrosion of iron and steel surfaces by an aqueous alkanolamine conditioning solution used to remove CO.sub.2 from a gas stream is effectively inhibited by a combination of a vanadium containing ion and a soluble cobalt salt. This system allows the use of higher amine concentrations which in turn allows a higher carbon dioxide loading with low corrosion thereby improving the energy efficiency of the gas sweetening process.

Abstract: Alkyl-substituted bicycloalkyl ether compositions useful in the preparation of synthetic lubricant compositions are obtained by reacting an alkyl-substituted 2-norbornene with a monohydric alcohol in the presence of an acidic catalyst.

Abstract: A process is provided for recovering substantially pure triethylenediamine in liquid lower alkylene diol solutions directly from the crude triethylenediamine reaction mixture without resort to a need to purify the triethylenediamine by crystallization. The process includes initially admixing a lower alkylene diol with a crude triethylenediamine liquid reaction product mixture. The admixture thus formed is then heated to remove water and other low boiling impurities. The crude triethylene diaminediol bottoms mixture is then codistilled to recover a pure triethylene diamine product in diol solvent which can be used directly to catalyze urethane systems.

Abstract: Covers a new composition of matter comprising an acrylamide or methacrylamide monomer characterized by the following structural formula: ##STR1## where R.sub.1 is hydrogen or methyl, R.sub.2 and R.sub.3 are lower alkyl, R.sub.4 is a linear or branched alkyl group containing 7-20 carbon atoms, X is an anion of an organic or mineral acid having a valence m and A is a divalent lower alkyl group.

Abstract: A process is provided for recovering substantially pure triethylenediamine in liquid tertiary amine solutions directly from the crude triethylenediamine reaction mixture without resort to a need to purify the triethylenediamine by crystallization. The process includes initially admixing a tertiary amine with a crude triethylenediamine liquid reaction product mixture. The admixture thus formed is then distilled under conditions such that the triethylenediamine and tertiary amine codistill as a substantially pure triethylenediamine solute in liquid tertiary amine solution. The collected codistillate being substantially free of reaction by-products can be used directly to catalyze urethane systems.

Abstract: Covers a new composition of matter comprising an acrylamide or methacrylamide monomer characterized by the following structural formula: ##STR1## where R.sub.1, R.sub.2 and R.sub.5 are hydrogen or methyl, R.sub.3 and R.sub.4 are lower alkyl, n is an integer ranging from 1 to 6 and A represents an anion.

Abstract: Covers a new composition of matter comprising an acrylamide or methacrylamide monomer characterized by the following structural formula: ##STR1## where R.sub.1 is hydrogen or methyl, R.sub.2 and R.sub.3 are hydrogen or lower alkyl, R.sub.4 is a primary or secondary alkyl group or an alkaryl group, each group containing 6-25 carbon atoms, and n is an integer ranging from 2 to 30.

Abstract: A liquid phase synthesis of C-alkyl-triethylenediamines involves heating to elevated temperatures of from about 200.degree. C to 300.degree. C a suitable N-(2-hydroxyalkyl) piperazine feedstock in the presence of a catalytic amount of a pentavalent acidic phosphorus compound and then recovering the C-alkyl-triethylenediamine product from the resulting reaction product mixture.

Abstract: Covers a new composition of matter comprising a stable N-(.omega.-monoalkylaminoalkyl) acrylamide or methacrylamide monomer characterized by the following structural formula: ##STR1## where R.sub.1 and R.sub.2 are hydrogen or methyl, R.sub.3 is isopropyl or t-butyl and n is 2 or 3, with the proviso that when R.sub.1 is hydrogen, R.sub.3 is t-butyl. Also covers a method of preparing said monomer by condensing one mole of an acrylic or methacrylic compound with two moles of an appropriate amine to form an intermediate substituted amide, followed by heating said intermediate to split off one mole of reactant diamine leaving the desired substituted aminoalkyl acrylamide or acrylamide monomer.
