  • Patent number: 10781405
    Abstract: Detergent compositions comprising one or more surfactants and a polyetheramine composition are disclosed. The polyetheramine composition comprises a compound having a polyglycerol core and an aminoalkyl group or an oxidized aminoalkyl group that is bonded directly or indirectly to each available oxygen of the polyglycerol core. Optionally, oxyalkylene groups link available oxygens of the polyglycerol core to the aminoalkyl or oxidized aminoalkyl groups. Methods for laundering textile articles and other cleaning methods using the detergent compositions are also disclosed. The polyetheramines can use diglycerol, a convenient plant-based starter. Laundry detergents comprising the polyetheramines provide enhanced cold-water cleaning performance for greasy or oily stains compared with similar detergents formulated without the polyetheramines.
    Type: Grant

  • Patent number: 8692005
    Abstract: Provided are methods for decreasing the reaction time between an alkanolamine such as triethanolamine and a fatty acid alkyl ester such as, a triglyceride, a vegetable oil, a methyl ester, an ethyl ester, etc., a fatty acid, or a mixture thereof. The methods utilize a divalent zinc catalyst to facilitate and accelerate an esterification or transesterification reaction between the alkanolamine and the fatty acid, or fatty acid alkyl ester.

  • Publication number: 20100016163
    Abstract: There is provided is an adjuvant/dispersant for pesticide formulations (among other formulated uses) comprising at least one dialkyl alkanolamine such as dimethyl ethanolamine, at least one derivative thereof, or a combination thereof. Pesticide compositions comprising a pesticide, such as glyphosate, and the adjuvant/dispersant of the present technology and methods for enhancing the effectiveness of the pesticide, such as glyphosate, in an aqueous composition through the addition of the adjuvant/dispersant of the present technology are also disclosed. Solid pesticidal formulations comprising a pesticidal active ingredient and the adjuvant/dispersant of the present technology are also provided.

  • Patent number: 7087771
    Abstract: A method for making alkyl esters (e.g., methyl ester), such as biodiesel, from an oil source is described. The method involves converting the free fatty acids of the oil source into a mixture of mono-, di-, and tri-glycerides and subsequently transesterifying the newly formed glycerides as well as the originally present glycerides into fatty acid alkyl esters.

  • Publication number: 20040254387
    Abstract: A method for making biodiesel from a vegetable oil source is described. The method involves simultaneously reacting the free fatty acids and glycerides of the vegetable oil source with methanol, under pressure up to 250 psig, into fatty acid alkyl esters for use as biodiesel. The conversion is catalyzed by an acid at temperatures between about 80° C. to about 200° C.

  • Patent number: 6768015
    Abstract: A method for making alkyl esters, or methylester specifically, such as biodiesel, from an oil source is described. The method involves simultaneously reacting the free fatty acids and glycerides of the oil source with methanol, under pressure up to 500 psia, into fatty acid alkyl esters.

  • Patent number: 5103042
    Abstract: Polyethers having terminal allyl unsaturation are subject to hydrogenolysis by reaction with a hydrogen donor in the presence of a n-allyl complex forming catalyst. The product polyethers have extremely low levels of unsaturation, and thus are useful in preparing polyurethanes having improved properties and processing.
