  • Patent number: 9878976
    Abstract: The present invention provides a method for producing a high quality cationic surfactant, which is prevented from smelling and coloring, and has favorable storage stability. The production method includes the following step 1, step 2, step 3, and step 4: step 1: a step of obtaining an alkanolamine ester by reacting an alkanolamine with a fatty acid or a fatty acid alkyl ester without using hypophosphoric acid or a salt thereof; step 2: a step of obtaining a cationic surfactant by quaternizing the alkanolamine ester obtained in the step 1 with a dialkyl sulfate; step 3: a step of performing an oxidation treatment of the cationic surfactant obtained in the step 2; and step 4: a step of performing a reduction treatment of the cationic surfactant subjected to the oxidation treatment obtained in the step 3.

  • Patent number: 8841470
    Abstract: Chemically-modified fatty acids are prepared by reacting epoxidized fatty acids, their esters or triglyceride oils with amines of cyclic or aromatic hydrocarbons. The fatty acid derivatives produced are of the formula: wherein R is an H, branched or straight chain alkyl or alkenyl group, aromatic-containing group, glycerol, or glyceride, R? is a C3 to C29 aliphatic chain comprising one or more of the derivatized methylene groups of the formula: wherein R1 and R2 are independently selected from the group consisting of H, cyclic hydrocarbons, substituted cyclic hydrocarbons, and aryl groups, with the proviso that only one of said R1 and R2 may be H. These fatty acid derivatives have utility as antiwear/antifriction additives for industrial oils and automotive applications.

  • Publication number: 20010031883
    Abstract: Novel compounds derived from traditional semi- drying and non-drying oils featuring internally plasticizing and crosslinkable properties are disclosed and claimed. Preferred embodiments include acrylate or methacrylate esters of hydroxy long-chain olefinic compounds derived from castor oil or lesquerella oil. A process for the preparation of the novel compounds is also disclosed, which involves esterification reaction of ethylenically unsaturated carboxylic acids or its derivatives with substituted hydroxy long-chain olefinic compounds. These compounds are suitable for forming latices, which form films at low minimum film forming temperatures (MFT) ranging from −5 to 10° C. and cure to above ambient glass transition (Tg) polymers without the use of traditional organic cosolvents which contribute to environmental pollution via volatile organic compounds (VOCs) emissions. These latices are therefore useful in waterborne coatings, contact and pressure sensitive adhesives, and inks.

  • Patent number: 6072063
    Abstract: Ester quats of the formula (1) below are described: ##STR1## where RCO is an aliphatic acyl radical having 6 to 22 carbon atoms, R.sup.1 is a methyl radical, R.sup.2 is a C.sub.1 -C.sub.6 -alkyl radical, R.sup.3 is a C.sub.3 -C.sub.6 -alkyl radical and X.sup.- is a halogen anion. They are prepared by quaternizing the corresponding carboxylic acid ethanolamine ester compound with a methyl halide in the absence or presence of solvents. The ester quats of the invention have a low melting point. Furthermore, even in high concentration they are highly water soluble and, on account of their preparation, are obtained in high purity and free from toxic contents. These ester quats can be used in many ways and are suitable, for example, for preparing solid or aqueous formulations having a high surfactant effect.
