Patents by Inventor John F. Arnett

John F. Arnett has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • PLANT STEROIDS AND USES THEREOF
    Publication number: 20190083632
    Abstract: The invention relates to a drug conjugate including a drug and a plant steroid. The drug conjugate may target the drug for intestinal cell delivery, and thus may be used to treat diseases, including intestinal diseases, or to affect intestinal metabolism. The invention therefore also relates to treating intestinal diseases and affecting intestinal metabolism with the drug conjugate.
    Type: Application
    Filed: August 29, 2018
    Publication date: March 21, 2019
    Applicant: DAVIDSON LOPEZ LLC
    Inventors: MICHAEL DAVIDSON, JOHN F. ARNETT, SADIK ELSHANI, ROELOF RONGEN

  • Preparation of glycidyl ethers
    Patent number: 4284573
    Abstract: A process for producing glycidyl ethers of phenols is described which comprises the steps of:(1) reacting by contacting, in liquid phase, a phenol with excess epichlorohydrin in the presence of a catalytic amount of tetrahydrocarbyl phosphonium bicarbonate salt, to thereby produce a coupled reaction product comprising the corresponding propylenechlorohydrin ether of said phenol;(2) devolatilizing said coupled reaction product to remove excess epichlorohydrin and volatile by-products; and(3) contacting the devolatilized reaction product from Step (2) with aqueous base, thereby converting the propylenechlorohydrin groups of the coupled reaction product to glycidyl ether groups.This process is particularly useful in preparing low molecular weight liquid epoxy resins by the reaction of epichlorohydrin with bisphenol A.

  • Process for preparing tetrahydrocarbylphosphonium bicarbonate salts
    Patent number: 4266079
    Abstract: Certain tetrahydrocarbylphosphonium bicarbonate salts are produced by reacting a trihydrocarbyl(hydrocarbylcarboxymethyl)phosphonium hydroxide inner salt with water. For example, methyl tri-n-butylphosphonium bicarbonate salt was prepared in quantitative yields by heating tri-n-butylcarboxymethylphosphonium hydroxide inner salt in an aqueous methanol solution at 100.degree. C. for 3 hours.
