CHEMICAL ABSTRACTS
  • What are Chemical Abstracts
  • What will they help you find?
  • How are they organised?
  • How to search for a
  • Subject
  • Chemical substance
  • Formula
  • Author

3
CHEMICAL ABSTRACTS
  • Published by American Chemical Society
  • Abstracts (summaries) of published texts in field
    of chemistry
  • Most complete guide to the CHEMICAL literature
  • HWUL print version 1907-2001

4
COVERAGE/SCOPE
  • VERY comprehensive
  • Journal articles
  • Patents
  • Books
  • Reports
  • Conference proceedings
  • X Little quality control

ABSTRACTS SECTION
  • Each part of volume divided by subject
  • Biochemistry / organic chemistry, etc
  • Each subject divided by publication type
  • Journal papers / patents, etc
  • Each abstract numbered consecutively

9
INDEXES
  • Each volume of abstracts has a complete set of
    indexes-
  • Index Guide Formula
  • General Subject Patent number
  • Author CA registry number
  • Chemical Substance Ring system
  • Collective indexes
  • HWUL has 1907-1976 incomplete

    interest
  • Title
  • Author/s
  • Source
  • Journal name / volume number / part number /
    pages
  • Patent number

18

    those years eg vols 134/135

19
SUBSTANCE NAME SEARCH - INDEX GUIDE
  • Starting point for substance name search
  • Thesaurus of preferred terms used by CA

CHEMICAL SUBSTANCESEARCH - ABSTRACTS SECTION
  • Look up the abstract number to find the abstract

135 330653u Absorption of Maillard reaction
volatiles by polymers. Bressa, Francesca Steel,
Robert J Dalla Rosa, Marco (Dipartimento di
Scienze degli Alimenti, University of Udine,
33100 Udine, Italy). Packag. Technol. Sci 1996,
9(5), 255-263 (Eng), Wiley. Correction of CA 126
5904p. The antioxidant properties of Maillard
reaction volatilities (MRV) have been
demonstrated in previous studies in particular a
significant antioxidant activity of MRV on the
oxidn. of heat-treated soybean oil was found.
These findings offer an opportunity to use MRV to
protect foods susceptible to oxidative
deterioration. . . . . .
23
CHEMICAL SUBSTANCESEARCH - ABSTRACTS SECTION
  • Carefully note bibliographic details for items of
    interest
  • TITLE
  • AUTHOR/S
  • SOURCE
  • Journal name / volume number / part number /
    pages
  • Patent number

24
TIP for subject or substance name search
  • Avoid temptation to look directly in -
  • General Subject or Chemical Substance
  • Index
  • Look in Index Guide first
  • The Index Guide will point you to
  • the preferred / current subject or
  • chemical substance
  • cross-references for any new /
  • alternative name/s
  • Use preferred terms to look in General
  • Subject or Chemical Substance Index

FORMULA SEARCH
  • FORMULA INDEX quickest route
  • Have the formula in Hill System Order
  • Inorganic alphabetically by element symbols
  • Organic C first, H (if present) then remaining
    symbols in alphabetical order

26
FORMULA SEARCH
  • Identify formula eg
  • C3H2Cl6N2P2
  • Decide year range to search eg 1978
  • Look up your formula in the relevant Formula
    Index eg vols 88/89

27
FORMULA SEARCH-FORMULA INDEX
  • Look up the formula

28
FORMULA SEARCH-CHEMICAL SUBSTANCE INDEX
  • Search using the chemical name for your formula
    (found in the Formula Index)
  • 1,3,2,4-Diazadiphosphorine (64683-47-2)
  • - 2,2,4,4,5,6-hexachloro-2,2,4,4,-tetrahydro-
  • 64448-18-6, 15324z, 152731u

    Allg.
  • Chem. 1977, 434, 95-8 (Ger). Cyclization of
  • acrylonitrite with . . .

30
TIP for formula search
  • Formula Index can be used directly to locate
  • abstract numbers but . . . .
  • An additional search in Chemical Substance Index
    (using name found in Formula Index) will find
    papers on related substances not found in Formula
    Index

31
AUTHOR SEARCH
  • Identify authors
  • eg Kevin L Ash
  • Decide year range to search eg 2001
  • Look up your surname in the relevant Author Index
    for those years eg vols 134/135
  • Ash, Kevin L

GENERAL TIPS
  • If searching 1907-1976, unless you want to search
    for a specific year, use collective indexes
  • Start with most recent index and work back
  • Read the introduction to each index

34
GENERAL TIPS
  • Use INDEX GUIDE as a first step in General
    Subject or Chemical Substance searching
  • Chemical names change from volume to volume but
    CA Registry Number remains constant. Try
    searching using this.

35
FINDING FULL-TEXT
  • You will have found
  • Abstracts
  • Bibliographic details
  • Use abstracts to decide whether to follow up
  • Use bibliographic details to locate full-text

36
