Beilstein Handbook of Organic Chemistry

Beilstein Handbook of Organic Chemistry. This reference (55) is one of the most significant collections of data in organic chemistry. The physical and chemical properties of organic compounds are tabulated in more than 500 fields. Most of these fields are searchable, and a sample of the record for chlorobenzene [108-90-7] is shown in Table 3. 

Fluoran compounds developing colors are not new, having been well known since early times. For example, the Beilstein Handbook of Organic Chemistry, XIX describes many fluoran compounds developing colors from yellow to red. These include 3, 6 -dimethoxyfluoran (4 yellow), 3 -chloro-6 -diethylaminofluoran (5 vermilion), and 9 -diethylaminobenzo[a]fluoran (6 red). 

Beilstein. Beilstein [63], a structure and factual database covering organic chemistry, contains more than 7,688,485 substance records (3/2000). The organic substance records contain reviewed and evaluated documents from the Beilstein Handbook of Organic Chemistry as well as data from 120 journals in organic chemistry covering the period 1779 to the present. Beilstein Database is commercially available in several electronic formats.

Numeric. Researchers routinely use reported nunierie measurements and data in their work. Numeric databases include the Beilstein Handbook of Organic Chemistry, ihc Gmelin Handbook of Inorganic and Orgunomelallic Chemistry, properly daia networks the Materials Property Data Network Inc. (MPDt and Chemical Property Data Network (CPDNtl. and TDS NUMERICA. 

Beilstein File. Beilstein first went on-line on STN International in December 1988 with information on 350,000 compounds, and several months later it was also on Dialog. Beilstein Online now comprises data on five million compounds. The organic substance records contain the critically reviewed and evaluated documents from the beilstein Handbook of Organic Chemistry, main volume and supplements 1—5, which cover the chemical literature from 1779 through 1979. These evaluated data are indicated as Handbook Data in the notes of literature references. The Beilstein File also contains organic substance records for unreviewed excerpts from the primary literature from 1980 to 1991.

The method for obtaining phase diagrams is to find the required data in books on physical properties. Some examples are International Critical Tables (1924) Beilsteins Handbook of Organic Chemistry (1960) CRC Handbook (1984) D Ans, Lax Handbuch (1967) Ullmann s Encyclopedia of Industrial Chemistry (1988) Kirk-Othmer s Encyclopedia of Chemical Technology (1979) and VDI-Wdrmeatlas (1988).

MOLMOUSE (Input of organic MOLecules using a mechanical MOUSE) was developed within the Beilstein Database Project. The projected, numerical factual database BEILSTEIN-ONLINE represents a natural extension of the BEILSTEIN Handbook of Organic Chemistry which has been published for more than 100 years in more than 300 volumes. 

Beilstein Handbook of Organic Chemistry - The classic source of data on organic compounds, dating from the 18 century, Beilstein was converted to electronic form in the last decade of the 20" century. Over 8 million compounds and 5 million chemical reactions are now covered, with a broad range of physical properties as well as synthetic methods and ecolr cal data. The database is accessed by the CrossFire software... 

The projected, numerical factual database BEILSTEIN-ONLINE represents a natural extension of the Beilstein Handbook of Organic Chemistry which has been published for more than 100 years in more than 300 volumes. The Handbook together with the structure file cards of the literature period 1960-1980 (E-V Period) contain factual and structural information on more than 4 million compounds. The computer representation of organic chemical structures therefore constitutes the centre part of the database design. The chemical structure is described in a post-topological format. Not only constitutional information is included but also a complete stereochemical representation. Bond orders are replaced by electronic information. This allows a much more global and unique representation of tautomers. This paper gives an overview not only of the data structure of chemical compounds but also of its associated physical numerical data and keywords. 

Stereochemical Descriptors in the Beilstein Handbook of Organic Chemistry, printed in the preface to each volume of the Beilstein Handbook, or available separately from Springer-V erlag. 

A truly vast and ever-growing body of organic chemical information is recorded in the chemical literature and in online databases. In a research library practically all of it can be searched quickly through these databases and with the use of Chemical Abstracts, Beilsteins Handbook of Organic Chemistry, and the review literature. Because print resources are still available, those will be discussed briefly, but online sources will be the focus of this chapter. 

BEILSTEIN contains organic chemical structures, preparation and reaction information, and numeric property data of pure components. The source for the database is the Beilstein Handbook of Organic Chemistry. The online version includes more current non-evaluated data than the handbook.
