ENAMIDE PROCESS
20180215702 · 2018-08-02 ·

A convenient method for converting oximes into enamides is disclosed. The process produces enamides without the concomitant production of a large volume of metallic waste.

##STR00001##

The enamides are useful precursors to amides and amines.

ARTICLES HAVING SILVER ION a-OXY CARBOXYLATE OXIME COMPLEXES
20180151265 · 2018-05-31 ·

A precursor article has a substrate and a photosensitive thin film or a photosensitive thin film pattern on a supporting side. The photosensitive thin film and each photosensitive thin film patterns comprises a non-hydroxylic-solvent soluble silver complex that is represented by the following formula (I):


(Ag.sup.+).sub.a(L).sub.b(P).sub.c (I) wherein L represents an -oxy carboxylate; P represents an oxime compound; a is 1 or 2; b is 1 or 2; and c is 1, 2, 3, or 4, provided that when a is 1, b is 1, and when a is 2, b is 2. A photosensitizer that can either reduce the reducible silver ion or oxidize the -oxy carboxylate having a reduction potential can also be present. Such precursor articles can be irradiated with UV-visible radiation to reduce the silver ions to provide electrically-conductive metallic silver in thin films or thin film patterns in product articles or devices.

TIME RELEASED DELIVERY OF FUNCTIONAL CHEMICALS

The present invention provides a composition comprising an isocyanate, and a functional chemical, wherein the functional chemical is attached to the isocyanate at an active hydrogen atom of the functional chemical. The present invention offers a way of assuring that the isocyanate-attached functional chemical is released slowly over time at any stage of the oil and gas well lifecycle.
