Patent number: 11213558Abstract: The present invention relates generally to improved methods for the extraction and isolation of cannabinoids from hemp. More particularly, the present invention relates to a series of extraction and isolation processes employed to selectively enhance recovery of non-psychoactive cannabinoids and the like, from cannabis materials and extracts, while removing undesirable naturally occurring components that may be present including colorants, carbohydrates, sugars and waxes, and the like, as well as contaminants that may be present in source materials including bactericides, fungicides, insecticides, plant growth regulators, environmental pollutants, and processing aids, and the like. The present invention further relates to an isolate obtained using a series of extraction and isolation processes that has extremely high cannabinoid content present in a stable, flowable liquid form that is essentially free of detectable levels of psychoactive cannabinol components.Type: GrantFiled: May 16, 2018Date of Patent: January 4, 2022Assignee: Orochem Technologies, Inc.Inventors: Anil Rajaram Oroskar, David W.

Patent number: 8802843Abstract: Disclosed is a process for the production of d-tagatose from lactose after acid hydrolysis to provide a hydrolysate having 1 equiv of d-glucose and 1 equiv of d-galactose for each unit of lactose converted. More particularly, the invention relates to a process for the isomerization of d-galactose to d-tagatose and the use of a simplified separation scheme based on simulated moving bed (SMB) separation. The isomerization of d-galactose to d-tagatose is carried out in the presence of calcium oxide or calcium hydroxide. The process is useful for providing a simplified processing route to providing pure d-tagatose and glucose as two products from lactose hydrolysate. In an alternate embodiment, a process is disclosed for the production of d-tagatose from fermented lactose hydrolysate to provide a crystallized d-tagatose product. D-tagatose is useful as a food additive, as a sweetener, as a texturizer, as a stabilizer, or as a humectant.Type: GrantFiled: May 22, 2012Date of Patent: August 12, 2014Assignee: OROCHEM Technologies, Inc.Inventors: Anil R.

Process and adsorbent for separating ethanol and associated oxygenates from a biofermentation system
Patent number: 8658845Abstract: Disclosed is a process and an adsorbent for the separation of ethanol associated oxygenates from a dilute mixture of ethanol and associated oxygenates in water in the presence of organic compounds derived from a biofermentation process. After pretreatment, the separation is carried out in a simulated moving bed adsorption system employing an stationary phase adsorbent comprising fluorinated carbon or modified C18 silica gel selective for the adsorption of ethanol and associated oxygenates, such as 2,3-butanediol, with a mobile phase desorbent selected from the group consisting of methanol, ethanol, propanol, and methyl tertiary butyl ether. The process is useful for removing water from dilute aqueous mixtures of organic compounds comprising ethanol in dilute concentration in water and produced by fermentation, biomass extraction, biocatalytic and enzymatic processes which are not economically recoverable by conventional distillation methods.Type: GrantFiled: May 23, 2012Date of Patent: February 25, 2014Assignee: Orochem Technologies, Inc.Inventors: Anil R.

Publication number: 20130277304Abstract: The present invention relates to chiral separation column for use with supercritical fluid chromatography (SFC) containing a porous sub-2 chiral stationary phase agent that offered significant savings in run times and solvent use over the more conventional chiral columns using SFC methods. It was surprisingly discovered that SFC columns containing highly stable and backpressure resistant sub-2 micron stationary phase agents which were either coated or at least partially covalently bonded with polysaccharide or derivatized polysaccharide and which have an average particle diameter less than 2 microns can be obtained by maintaining a pore ratio of from 0.0042 to about 0.010 provide improved efficiency.Type: ApplicationFiled: February 27, 2013Publication date: October 24, 2013Applicant: OROCHEM TECHNOLOGIES, INC.Inventors: David W.

Patent number: 6670509Abstract: A process for oxygenating organic substrates such as aliphatic hydrocarbons has been developed. The process involves contacting the organic substrate with oxygen in the presence of a bicyclo imide promoter and a metal co-catalyst. The process is preferably carried out using sulfolane as the solvent. Optionally, the oxygenated product can be hydrogenated to give the corresponding alcohol which can optionally in turn be dehydrated to provide the corresponding olefin.Type: GrantFiled: April 11, 2002Date of Patent: December 30, 2003Assignee: UOP LLCInventors: Paul R.
