Patents chemistry

For someone trained in the disciplines of chemistry, patent law can be a fascinating career. It is not necessary, of course, to be skilled in all phases of chemistry to be a successful chemical patent lawyer. Once one has learned the general theories of chemistry and the vocabulary, it is not difficult for inventors, scientists, or engineers to explain to him the...

The word portal is often used for web sites that function as an entiy to a repo-sitoiy of information on almost any topic on the Internet. The following portal categories for chemical issues arc distinguished general chemistry sites substance information sites analytical chemistiy sites enviromnental chemistry sites toxicology and occupational health sites as well as patent seiwices [47],...

We have not indicated the reagents employed in the reactions by which ethylene and propene are converted to the compounds shown Because of patent requirements different companies often use different processes Although the processes may be different they share the common characteristic of being extremely efficient The industrial chemist faces the challenge of producing valuable materials at low cost Success in the industrial environment re quires both an understanding of chemistry and an... 

While the principal value of the book is for the professional chemist or student of chemistry, it should also be of value to many people not especially educated as chemists. Workers in the natural sciences—physicists, mineralogists, biologists, pharmacists, engineers, patent attorneys, and librarians—are often called upon to solve problems dealing with the properties of chemical products or materials of construction. Eor such needs this compilation supplies helpful information and will serve not only as an economical substitute for the costly accumulation of a large library of monographs on specialized subjects, but also as a means of conserving the time required to search for... 

Oxidative Carbonylation of Ethylene—Elimination of Alcohol from p-Alkoxypropionates. Spectacular progress in the 1970s led to the rapid development of organotransition-metal chemistry, particularly to catalyze olefin reactions (93,94). A number of patents have been issued (28,95—97) for the oxidative carbonylation of ethylene to provide acryUc acid and esters. The procedure is based on the palladium catalyzed carbonylation of ethylene in the Hquid phase at temperatures of 50—200°C. Esters are formed when alcohols are included. Anhydrous conditions are desirable to minimize the formation of by-products including acetaldehyde and carbon dioxide (see Acetaldehyde). 

PHARM. This file contains bibliographic records of patents ia the fields of pharmaceutical chemistry and biology. Coverage iacludes European, Erench, and U.S. patents from 1986, German and British from the 36th week of 1992, PCT from 1993, and Erench Special Patents for Medical Compositions (BMS) from 1961. Records emphasize the pharmaceutical aspects of the iavention. PHARM is produced by INPl (97). 

The chemistry of melamines and phenoHcs is quite similar. In both cases formaldehyde [50-00-0] is added to the reactive sites on the patent ring to form methylol phenols (3) or methylol melamines (4) (see Phenolresins Aminoresins). There ate six reactive sites on the triazine ring of melamine [108-78-1] (1) so it is possible to form hexamethylolmelamine. However, the most common degree of methylolation is 1.5—2.0. The ortho and para positions of phenol ate active thus phenol can be trimethylolated (2). However, as with melamine, lower degrees of methylolation such as 1.2—2.5 ate...
