    摘要: Novel compounds of the general formula ##STR1## (m = 0 or 1; n = 2 or 3 and R = H or CH.sub.3) are produced by reacting a 2-aminoalkyl alkylene urea with an allyl ester of a carbonylic acid. Among the particular allyl esters disclosed as reactants are diallyl carbonate, allyl and methallyl chloroformate, diallyl and dimethallyl oxalate. The recovered allyl esters of the alkyleneureido amic acid compounds find particular use as functional comonomers for imparting wet adhesion properties to emulsion systems containing vinyl ester polymers used in paints and coating compositions.

    摘要: This invention relates to a process for producing ring alkylated aromatic amines where the alkyl substituent is ortho to the amino group by reacting an N-alkylated aromatic amine with a C.sub.2-10 olefin in the presence of a solid phase acidic catalyst, e.g., silica-alumina or a zeolite. High conversion and selectivity is achieved by maintaining a mole ratio of olefin to amine of from about 1-10:1 and an operating pressure of at least 50 psig.

    摘要: This invention relates to a process for producing mono-ortho-ethyl- aniline in high selectivity and at high conversion using a silica-alumina catalyst. The reaction is carried out using a fixed bed reactor. Diethylaniline derivatives are avoided by maintaining preselected mole ratios of ethylene to aniline, preselected temperatures and preselected reaction times.
