554156000 | Group IA or IIA metal containing reactant (e.g., forming a soap from fat and alkali, i.e., saponification, etc.) | 9 |
20090131700 | Production of fatty acid and fatty acid ester - The present invention concerns a process for forming a fatty acid, a fatty acid ester or a mixture thereof from a soap-comprising starting material, in which process a metal-ion forming agent is added to the starting material, whereby a mixture is formed, which contains an insoluble phase and a liquid phase, the insoluble phase is separated from the liquid phase, and an acid is added into the insoluble phase to form a fatty acid, or a monohydric alcohol and an acid catalyst are added to form a fatty acid ester, whereby two phases are formed, an aqueous phase and an organic phase, or, first, an acid is added and then a monohydric alcohol and an acid catalyst are added into at least a portion of the formed fatty acid to esterify the fatty acid. | 05-21-2009 |
20110282084 | CASTOR OIL FATTY ACID BASED ESTOLIDE ESTERS AND THEIR DERIVATIVES AS POTENTIAL LUBRICANT BASE STOCKS - Castor oil was hydrolysed to castor fatty acids and self condensed to get a ricinoleic acid-based estolide of about acid value. The carboxylic group of the estolide on subsequent esterification with linear or branched chain alcohols and also on acetylation of free hydroxy group yielded castor oil fatty acids based estolide esters and their acetates. All the products were evaluated for total acid number (TAN), viscosity, viscosity index, pour point, flash point, and copper strip corrosion and found to be potential lubricant basestocks. | 11-17-2011 |
20150361384 | METHOD AND APPARATUS FOR MAKING SOAP - The present invention is directed towards a method and apparatus for making soap. According to one embodiment, a soap making apparatus comprises a water vessel that holds water, an oil vessel that holds an oil mixture, a lye container that accepts enclosed lye capsules and a microcontroller that controls a mixture of ingredients that is discharged from the water vessel, oil vessel and lye vessel to produce one or more soap bars made. | 12-17-2015 |
20160376536 | New methods for making soap powder - Methods for making soap powder of the current invention using a double boiler system in which the direct heating and boiling of the mixture was avoided. A method for making soap powder of the current invention at room temperature. The soap powders of the current invention of a preferred composition of 49 g sodium hydroxide, 250 ml vegetable oil and 220 g water. | 12-29-2016 |
20220135510 | COMPOSITIONS AND METHODS OF PREPARATION THEREOF - Described herein are methods of preparing compounds derived from triglycerides or condensation polymers such as polyesters and/or polyamides. The methods may include subjecting triglyceride or condensation polymer containing matter to mechanical processing in the presence of a nucleophile. | 05-05-2022 |
554157000 | Organic material, in addition to a fatty material, utilized or plural diverse fatty materials utilized (e.g., as solvent, reaction promoter, etc.) | 3 |
20090326252 | PROCESS OF MANUFACTURING OF FATTY ACID ALKYL ESTERS - Processes for preparation of fatty acid alkyl esters are described herein. The processes include contacting fatty acid glycerides with alcohols in the presence of a catalyst separating the reaction products from the catalyst, and separating the fatty acid alkyl esters from the reaction products. The catalyst includes a metal from Group VIB of the Periodic Table, a metal from Group IIIA of the Periodic Table, and an element from Group VA of the Periodic Table. | 12-31-2009 |
20130006006 | Chemicals Produced from Oil-Bearing Microbial Biomass - Chemicals prepared from oleaginous microbes and related methods are provided. | 01-03-2013 |
20140194634 | Method for preparing high purity biodiesel - Disclosed is a method for preparing high purity biodiesel from crude oils. The method comprises the steps of: pre-treating the crude oil raw material to remove impurities; pre-esterifying the pre-treated crude oil raw material under the effect of a catalyst of concentrated sulfuric acid; and then carrying out an ester exchange reaction in the presence of an alkali catalyst; recycling methanol, and separating glycerol, so as to obtain a crude fatty acid methyl ester; and subjecting the obtained fatty acid methyl ester to purification, distillation and segmentation to obtain a high-purity fatty acid methyl ester. | 07-10-2014 |
554158000 | Inorganic boron, halogen, phosphorus, silicon, sulfur, elemental metal, or additional metal containing compound utilized (e.g., utilizing inorganic agent for "salting out", bleaching, purifying, etc.) | 1 |
20140364637 | Process for Making Esters - The invention relates to a process for making esters, in particular biodiesel, using heterogeneous catalysts. The invention provides a process for making biodiesel, in particular FAME, which process is versatile and robust. The process of the invention can be carried out continuously, in particular in a fixed bed reactor or a slurry reactor and may be operated in a continuous fashion. In accordance with the invention, the transesterification reaction of triglycerides is carried out using a heterogeneous catalyst that comprises a Group 4 silicate and less than 3 wt. % Na in the presence of at least one acid compound. | 12-11-2014 |
