  • Process for the preparation of formamide compounds
    Patent number: 4529822
    Abstract: This invention relates to preparing formamide compounds in a process which comprises reacting an amine with a formylalkanolamine in the presence of carbon monoxide in which the mole ratio of amine to formylalkanolamine ranges from 0.2:1 to 5:1. The reaction is conducted at a temperature ranging from about 50.degree. to 300.degree. C. and a pressure ranging from about 100 to 10,000 psig. The amine employed in the reaction has the formula: ##STR1## wherein R' is hydrogen, an alkyl group of 1 to 10 carbon atoms, cyclohexyl, or --R"--O--R'", wherein R" is a divalent alkylene group of 2 to 4 carbon atoms and R'" is an alkyl group of 1 to 3 carbon atoms; and R is hydrogen or an alkyl group of 1 to 10 carbon atoms. The formylalkanolamine employed in the reaction has the formula: ##STR2## wherein R is an alkylene group of 1 to 3 carbon atoms, z is 0 or 1 and y is 1 or 2 and the sum of y and z is 2.

  • Process for the preparation of formylalkanolamines
    Patent number: 4510326
    Abstract: A process for the preparation of a formylalkanolamine which comprises reacting carbon monoxide with an alkanolamine at a temperature ranging from about 60.degree. to 300.degree. C. and at a pressure ranging from about 100 to 10,000 psig, said alkanolamine being represented by the formula:RNH.sub.x --CH.sub.2 --(X).sub.z --CH.sub.2 --OH).sub.yin which x is 0 or 1, R is hydrogen, a methyl or an aminoethyl radical with the proviso that R is hydrogen when x is 0, y is 1 or 2 and the sum of x and y is 2, X is a divalent radical from the group consisting of --CH.sub.2 -- and --CHOH--, and z is 0 or 1.

  • Alkyl norbornyl ether sulfonates useful for solubilizing petroleum sulfonates in oil fluid brine solutions
    Patent number: 4412926
    Abstract: Alkyl norbornyl ether sulfonates are prepared by reacting, for example, an allyl alcohol ethoxylate with an alkyl norbornene in the presence of an acid catalyst. The allyl ethers so obtained are subsequently sulfonated. These compounds, which exhibit a high degree of detergency, are useful for solubilizing petroleum sulfonates in oil fluid brine solutions.
