The solvent database was developed to contain data vital in any solvent application in one comprehensive source. Total 1627 solvents included in the database. It consists of 60% solvents having generic chemical name and remaining are industrial solvents which are mixtures of component solvents. The solvents in the database belong to several groups including aliphatic and aromatic hydrocarbons, ethers, esters, aldehydes, ketones, alcohols, terpenes, amines, acids, CFC, HFC, HCFC, FC, other chlorine containing compounds, glycols, and polyhydric alcohols.
In addition to the solvent applications, database is very useful tool for those who are interested in curatives (for example, a large collection of amines and polyhydric alcohols are included), common monomers also used as solvents, and low boiling liquids used in aerosols. The large number of the solvents and the data fields makes this database with almost 70,000 individual data the largest and the most comprehensive database on solvents.
The solvent database is divided into five sections: General, Physical, Health, Environmental, and Use. Information on the selected solvent can be accessed by clicking on any of the above tabs. The database has 140 data fields. Each screen contains solvent name and its chemical structure. The data can be viewed on screen and printed in a predefined format.
General: In the General section the following data are displayed: Name, CAS number, Acronym, Chemical category, Empirical formula, IUPAC name, Mixture, Moisture contents, Molecular weight, Other properties, Product contents, EC number, RTECS number, and Synonyms 1, 2, 3.
Physical: The Physical section contains data on Name, CAS number, Dielectric constant, Acceptor number, Acid dissociation constant, Aniline point, Antoine temperature range, Antoine constants A, B, and C, Boiling temperature, Coefficient of thermal expansion, Color, Corrosivity, Donor number, Electrical conductivity, Evaporation rates with butyl acetate=1 and ether=1, Freezing temperature, Hansen solubility parameters dD, dP, and dH, Molar volume, Heat of combustion, Enthalpy of vaporization, Enthalpy of vaporization temperature, Henry's law constant, Hildebrand solubility parameter, Kauri butanol number, Odor, Odor threshold, pH, Polarity parameter, ET(30), Refractive index, Solubility in water, Specific gravity, Specific gravity temperature, Specific heat, State, Surface tension, Thermal conductivity, Vapor density, Vapor pressure, Vapor pressure temperature, Viscosity, and Viscosity temperature.
Health: The Health section contains data on Name, CAS number, Autoignition temperature, Carcinogenicity: IRAC, NTP, OSHA, Mutagenic properties, Reproduction/developmental toxicity, DOT class, TDG class, ICAO/IATA class, packaging group, IMDG class, packaging group, UN/NA hazard class, UN packaging group, Proper shipping name, Explosion limits: lower and upper, Flash point, Flash point method, LD50 dermal (rabbit), LC50 inhalation (rat), LD50 oral (mouse), LD50 oral (rat), Maximum concentration during 30 min exposure (NIOSH-IDLH), Maximum concentration at any time: ACGIH, NIOSH, OSHA, Maximum concentration during continuous exposure for 15 min: ACGIH, NIOSH, OSHA, NFPA flammability, health, reactivity, HMIS flammability, health, reactivity, Route of entry, Ingestion, Skin irritation, Eye irritation, Inhalation, First aid: eyes, skin, inhalation, Chronic effects, Target organs, Threshold limiting value: ACGIH, NIOSH, OSHA, UN number, UN risk phrases, and UN safety phrases.
Environmental: The Environmental section contains data on Name, CAS number, Aquatic toxicity, Bluegill sunfish (96-h LC50), Daphnia magna (96-h LC50) and (48-h LC50), Fathead minnow (96-h LC50), Rainbow trout (96-h LC50), Bioconcentration factor, Biodegradation probability, Biological oxygen demand (20-day test) and (5-day test), Chemical oxygen demand, Atmospheric half-life, Hydroxyl rate constant, Global warming potential, Montreal protocol, Partition coefficient, Ozone depletion potential (CFC11=1), Ozone rate constant, Soil absorption constant, Theoretical oxygen demand, Urban ozone formation potential (C2H4=1), UV absorption.
Use: The Use section contains information on Name, CAS number, Manufacturer, Outstanding properties, Potential substitutes, Recommended for polymers, Features & benefits, Processing methods, Recommended dosage, and Recommended for products.
The solvent search is a simple process which can be done in the several ways. The most common is search by a solvent name. In this case, the program searches through the list of synonyms and proposes choices. Searching is easy by typing the first letter or two of their name which moves list to the location of solvent. Solvents can also be searched by CAS number, empirical formula, or any other property, or simply by browsing the list of solvents. In addition to searching capability and viewing data on individual solvents, solvents can be sorted according to values of any property. This operation is accomplished by clicking on the property tab and selection of the required search term from a pull-down menu. The operation returns a selection of solvents for which data exist for the selected property. The solvent property can be viewed on the screen and used for evaluation of solvent suitability for a chosen task or solvent selection for application as well as solvent comparison.
The above description shows that operation of the database is so simple that it does not require any computer skills. The appropriate computer for database use is a PC-based computer with Pentium processor (or other processor of similar speed) having a screen with resolution of at least 600 by 800 operating under Windows 2000 or higher. Program contains operation manual which explains further details of operation.
In summary, the database is a very powerful tool, considering that it is currently to our knowledge (and it has been for the last 6 years) the largest existing database on solvents. The database is an excellent companion to the Handbook of Solvents because data in the database do not repeat information or data included in the book (Handbook of Solvents also contains large number of numerical data not included in the database). The printed form of this database would require at least 8000 pages in a book format. This is several times larger volume than was available in any past book containing information on the solvent properties.
The following changes and updates have been made from the previous edition:
- Previous edition had 104 fields and present edition has 140 fields.
- 2nd edition had 3 sections (General, Physical & Chemical Properties, and Health & Safety), the 3rd version has 5 sections (General, Physical, Health, Environmental, and Use).
- 2nd edition had 1141 records; the 3rd edition has 1627 records.
- Many new data were added increasing amount of information in the database by at least 65%.
- Data on commercial solvents were verified and updated to the presently accepted values (records include current set of values and details of specifications given by manufacturers).
- Customer suggestions regarding 2nd edition were implemented and erroneous data corrected.
- 3rd edition includes a full collection of solvents which are on High Production Volume list (see EPA) which includes all chemicals which are either manufactured or imported at volume larger than 1 million pounds per year.
- Units of measurement were changed to SI (unless other units are more frequently used)
- Database operation was further simplified making it the easiest possible to use database. SHOW LESS READ MORE >
