Complete Chemical Name

Working examples take the familiar form of standard operating procedures that a chemist records in a scientific notebook as he carries out chemical reactions. They state concisely which compounds of the invention arise from these reactions. The accompmying list of compounds gives their complete chemical names or sometimes structural drawings. It identifies the compounds, which in either case can be recognized by the physical property or properties that the example furnishes. 

All the names of a substance, recorded by Chemical Abstracts Service are laid down in the field Complete Chemical Name (CN). The CA Index Name - the now valid CA nomenclature - is found at the top of the list (Sect. 2.1.3.2). Other possible CA Index Names as well as further systematic names, trade names, etc. follow. 

Complete Section 1.4 only if you are claiming the specific chemical identity of the toxic chemical as a trade secret and have marked the trade secret block in Part I. Section 1.1 on page 1 of Form R. Enter a generic chemical name that is descriptive of the chemical stmcture. You must limit the generic name to seventy characters (e.g., numbers, letters, spaces, punctuation) or less. Do not enter mixture names in Section 1.4 see Section 2 below.

Paterson and Mackay (1985), Mackay and Paterson (1990, 1991), and a recent text (Mackay 2001). Only the salient features are presented here. Three evaluations are completed for each chemical, namely the Level I, II and III fugacity calculations. These calculations can also be done in concentration format instead of fugacity, but for this type of evaluation the fugacity approach is simpler and more instructive. The mass balance models of the types described below can be downloaded for the web site www.trentu.ca/cemc... 

Each time the number of carbon atoms is increased by one (with the addition of a CHOH group) a new carbohydrate is produced which has a chemically distinct form and a completely different name. Because this group... 

The CALL facility allows the expert system to access software external to the LISP program. Included with the CALL is the name of a LISP function which handles the outside software. In the case of the fact CHEMICAL NAME, the LISP function executes a FORTRAN program which allows the user to either retrieve the structure of a previously entered compound or enter a new one. The program also breaks the chemical structure into its functional groups. When the FORTRAN program terminates, the LISP function updates the list of facts, and inserts the name into CHEMICAL NAME and the functional groups into FUNCT GROUPS. These FACTS are then available to the expert system. In this way, access to outside software is completely data driven. 

The conventional way to remove hair from cowhides is to use harsh chemicals, namely slaked lime and sodittm sttlfide. These chemicals completely dissolve the hair and open up the fiber stmctrrre. Errzyme-assisted tmhairing, with or without recovery of the hair, is closely related to the conventional process. However, just by adding an ertzyme, it is possible to reduce the reqrrirements for soditrm strlfide and lime. This process gives a very clean pelt, a high area yield and resrrlts in fewer chemicals in the waste water. 

Thus, there were serotonin 1 receptors, and then there were 1 and 2 receptors, and then la and lb and 2a and 2b receptors, and on and on. These are called 5-HT receptors, since the chemical name for serotonin is 5-hy-droxytryptamine, and the scientist would never want to let the layman know just what he is talking about. DOI has been synthesized with a variety of radioactive iodine isotopes in it, and these tools have been of considerable value in mapping out its brain distribution. And by extrapolation, the possible localization of other psychedelic compounds that cannot be so easily labelled. A small neurochemical research company on the East Coast picked up on these properties of DOI, and offered it as a commercial item for research experiments. But I doubt that they are completely innocent of the fact that DOI is an extremely potent psychedelic and that it is still unrecognized by the Federal drug laws since, in their most recent catalog, the price had almost doubled and a note had been added to the effect that telephone orders cannot be accepted for this compound. 

The ability to represent uniquely a chemical compound is a fundamental requirement for storage or transmission of chemical information. We define compounds by their molecular structure, as shown in two-dimensional diagrams or stored in computers. Pronounceable names have been developed for oral and written communication, ranging from the trivial, containing no structural information, to completely systematic names, which can be decoded to yield the original structure. However, the application of systematic nomenclature to complicated structures requires expert knowledge of elaborate systems of nomenclature rules. The use of systematic nomenclature to convey information about the increasingly complex molecular systems handled by today s chemists is both laborious and inefficient. 

The names of chemical compounds may consist of one or more words, and they may include locants, descriptors, and syllabic portions. Locants and descriptors can be numerals, element symbols, small capital letters, Greek letters, Latin letters, italic words and letters, and combinations of these. Treat the word or syllabic portions of chemical names just like other common nouns use roman type, keep them lowercase in text, capitalize them at the beginnings of sentences and in titles, and hyphenate them only when they do not fit completely on one line. 

Do not use hyphens to separate the syllables of a chemical name unless the name is too long to fit on one line. Appendix 12-1 is a list of prefixes, suffixes, roots, and some complete words hyphenated as they would be at the end of a line.

In the course of the review, several unique characteristics of the stratosphere will become apparent. We will identify examples of how the mechanistic details of a single reaction can dramatically affect predictions of stratospheric change into the next century. This is a particularly fascinating aspect of these studies — namely that while a reasonably complete (chemical) description of the stratosphere requires approximately 200 reactions, details of the reaction mechanism of a single process can alter predictions of global ozone depletion by more than a factor of three. 

Because chemical names are subject to a certain amount of developmental change and because complex compounds are difficult to name and lend themselves to correct naming in more than one way, CA as long ago as 1920 adopted the practice of indexing compounds by systematically arranged molecular fonnulas (these do not vary), but it did not abandon the use of words also in the indexing of compounds. Readers are given their choice, with both the index by names and the index by formulas made complete. Entry in the Formula Index of the simpler and commoner compounds in the form of cross references to the Subject Index is re-...
