CHE 432: Principles of Chemical Engineering Design : Thermodynamic Properties

Library and internet resources for CHE 432 assignments.

Introduction

Property data can be some of the most difficult information to find.  

There are many resources to look in and because each chemical substance and property may be called many different names, each resource must be searched by each of those different terms.  Even more disconcerting - there's no guarantee the property data you want has ever been determined (either experimentally or theoretically), so when you don't find the information is it because the data doesn't exist or is it because you aren't looking in the right place and/or using the right terminology?  

Below you'll find instructions on what resources to use and what search terms and strategies to look for.  These tips may help you be more succesful in your search and to spend less time doing it.

Know What You Need

Do you know what you're looking for and will you recognize when you see it? 

To find property data you need to know the following before you start your search:

  • Synonyms - Is there different terminology that describes the same property?  If there are synonyms, you must search each of those synonyms in every resource you try.   It's time consuming but a necessity; you don't know which term is being used in resource until you try to find it.  So when looking for the heat of formation of a substance, don't forget that the resource may call it enthalpy of formation and so you need to search that term also.   Many of the handbooks listed below will help you find the different terminology for each substance and property.

  • Symbol/Unit of Measurement - Many resources, especially handbooks in a print format, display property data using the property symbol and units in the table headers rather than the terminology.  If you search by words and are sent to a table in which you can't find those words, look for the symbols of that property.  Ex. enthalpy of formation = ΔH°f kJ/mol (or ΔH°f kcal/mol, etc.)   Many of the handbooks listed below will help you find the symbol and units for your property. 
      
  • Formula - What is the formula for that property?  If you can't find the property value itself, can you find the formula components so that the property can be calculated?

Where to Look ... Handbooks

When property data is frequently used, a publication may be created that brings together all the data from the literature into one place - these publications may be handbooks (a single volume work summarizing a subject, especially formulas and data) or simply a data compilation in print (tables) or database format. 
 

Online Sources:

  1. Knovel
    Includes:
  2. CRC Handbook of Chemistry and Physics
  3. NIST Chemistry WebBook
  4. NIST Data Gateway
  5. SciFinder
    To find the property data: Click on Explore Substances link at the top -> Click on Substance Identifer link in the left column -> Enter substance name -> In results list, click on Substance Detail link for the appropriate substance -> Scroll page down to Predicated and Experimental Properties sections.  To see the article/patent/report from which that data was taken, click on the number in the right hand column for the row.

Where to Look ... Bibliographic Indexes

Some bibliographic indexes have "added value" indexing which can help retrieve journal articles that contain property data, especially if the property is a major concept of the article.
 

SciFinder
In addition to using SciFinder's data compilation for each substance, you can also use the regular searching features to find other possible articles/patents/reports for the property. 

  1. For simple, one-word substances, you can use the Research Topic search, type in the "property of the substance" (ex. density of acetone);

  2. For more complex named substances, click on "Substance Identifer" under "Substances" in the left-hand column.  Enter substance name in the search box; in the results list, click on the "Properties" link underneath the substance box to see data that SciFinder has compiled on that chemical; use the References link to search the literature by keyword. 

Where to Look ... Full Text Searching

Searching the full text of journal articles can help you find property data that is "buried" deep within articles and is especially useful for finding data that is not a major concept of the article.
