These terms are not guaranteed to refer to the same concept across time but are guaranteed to be consistent within a particular OWL export. Use 'cycAnnot:externalID' for unambiguously referring to a concept across OWL exports or across Cyc inference engines. methyldichlorophosphine Methyldichlorophosphine The chemical with formula CH3Cl2P.

A collection of collections and a specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjNlZwpEbGdrcN5Y29ycA" class="cyc_term">ChemicalSubstanceType</a>. Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvUCoPtoTQdaZVdw2OtjsAg" class="cyc_term">ChemicalCompoundTypeByChemicalSpecies</a> is a specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj27ZwpEbGdrcN5Y29ycA" class="cyc_term">PartiallyTangible</a> whose instances are defined _only_ by their chemical composition -- not by their physical state or any other property. Instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvUCoPtoTQdaZVdw2OtjsAg" class="cyc_term">ChemicalCompoundTypeByChemicalSpecies</a> are collections whose instances are completely uniform with each other in terms of chemical structure, e.g., <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjAHZwpEbGdrcN5Y29ycA" class="cyc_term">Water</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVkLW5wpEbGdrcN5Y29ycA" class="cyc_term">Caffeine</a>, and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj8YZwpEbGdrcN5Y29ycA" class="cyc_term">IronOxide</a>. This collection does not include the chemical elements -- such as <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjIQpwpEbGdrcN5Y29ycA" class="cyc_term">Carbon</a> and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjIyJwpEbGdrcN5Y29ycA" class="cyc_term">Oxygen</a>, since there can be multiple types that molecules can be formed out of a single element, e.g. O2 and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwQCj4pwpEbGdrcN5Y29ycA" class="cyc_term">Ozone</a>. Use the broader collection, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjNlZwpEbGdrcN5Y29ycA" class="cyc_term">ChemicalSubstanceType</a>, for substances which have a general chemical specification, that is, whose instances do not have exactly the same chemical composition but fall within certain specifications, e.g., <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWXHLJwpEbGdrcN5Y29ycA" class="cyc_term">DNAStuff</a>. chemical compound ChemicalCompoundTypeByChemicalSpecies PartiallyTangible A subcollection of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4ro3lluGJHQdiVxrZReHS-jQ" class="cyc_term">EnduringThing_Localized</a> and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAxJwpEbGdrcN5Y29ycA" class="cyc_term">TemporalThing</a>. Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj27ZwpEbGdrcN5Y29ycA" class="cyc_term">PartiallyTangible</a> has a tangible (i.e. material) part and a temporal extent (i.e. it exists in time). It might or might not also have an intangible part. For example, a particular copy of a book is made of matter, has temporal extent, and also has an intangible part: the information content of the text markings on its pages. tangible thing methyldichlorophosphine Methyldichlorophosphine The chemical with formula CH3Cl2P.
