Isocyanate esters (i.e., compounds containing the isocyanate group, -N=C=O, bonded directly to carbon, which carbon may be single bonded to any atom but may be multiple bonded only to carbon)
| 137 |
560307000 |
Esters having the -S(=O)(=O)-S- group, wherein the divalent sulfur is bonded directly to carbon, which carbon may be single bonded to any atom but may be multiple bonded only to carbon (e.g., thiolsulfonate esters, etc.) | 2 |
20120088927 | Methods for the Formation of Hydrogels Using Thiosulfonate Compositions and Uses Thereof - The present invention provides both crosslinked polymer compositions capable of forming hydrogels upon exposure to an aqueous environment and thiosulfonate hydrogel-forming components. The thiosulfonate hydrogel-forming components of the invention are preferably multi-arm thiosulfonate polymer derivatives that form a crosslinked polymer composition when exposed to a base without requiring the presence of a second cross-linking reagent, redox catalyst, or radiation. Methods for forming hydrogel compositions, as well as methods for using the hydrogels, are also provided. | 04-12-2012 |
20120088928 | USE OF S- (3-AMINOPROPYL)THIOSULFURIC ACID OR METAL SALT THEREOF - Use of S-(3-aminopropyl)thiosulfuric acid and/or a metal salt thereof for improving the viscoelastic properties of a vulcanized rubber. | 04-12-2012 |
560302000 |
Compounds having the group -C(=X)-X-nX-, wherein the X's may be the same or diverse chalcogens, nX is a divalent chalcogen or a chain of divalent chalcogens single bonded to each other, and the terminal X is bonded directly to carbon, which carbon may be single bonded to any atom but may be multiple bonded only to carbon (e.g., percarboxylate esters, etc.) | 2 |
20120022286 | PROCESS FOR PRODUCING PERFLUORO ORGANIC PEROXIDE - To provide a process for safely producing a perfluoroacyl peroxide with good productivity. | 01-26-2012 |
20150336886 | METHOD FOR PHASE TRANSFER SYNTHESIS OF ORGANIC PEROXIDES - Processes and systems for synthesizing organic peroxides are provided. One or more of the reactions described herein may be performed in a continuous reactor, optionally including at least one microscale reaction channel. Additionally, at least one phase transfer catalyst may be used to facilitate reaction of components present in a multiphase reaction mixture. | 11-26-2015 |
560312000 |
Hydroxamate esters or chalcogen analogues thereof (i.e., compounds having the -C(=X)-NH-X- group, wherein the X's may be the same or diverse chalcogens and substitution may be made for hydrogen only, and wherein the single bonded X is bonded directly to carbon, which carbon may be single bonded to any atom but may be multiple bonded only to carbon) | 2 |
20110207960 | Process For The Preparation Of Iodinated Contrast Agent - The present invention relies on a process for the preparation of non ionic iodinated contrast agents and, in more details, it relates to a process for the preparation of Iopamidol in high yields and with a high degree of purity. In more details, the invention discloses a process for the preparation of a compound of formula (III) comprising the 5 condensation reaction a compound of formula (II) with 2-amino-1,3-propandiol, being said reaction carried out in an aprotic dipolar solvent and in the presence of an alkaline or alkaline rare earth metal oxide or hydroxide. | 08-25-2011 |
20140288326 | NOVEL PROCESS - A direct acid catalyzed intermolecular electrocyclic rearrangement process for the preparation of linear and cyclic homoallylic ester and amides. A one step intermolecular electrocyclic rearrangement process includes the step of reacting a beta, gamma-unsaturated aldehyde or ketone, in which the beta, gamma-unsaturation is not part of an aromatic ring, with another aldehyde or a secondary aldimine in the presence of an acid. | 09-25-2014 |
