Great Starting Points--Encyclopedias or Rules of Thumb
These e-books in Chemistry and Chemical Engineering, are great places to start, including Plant Design and Operation and data on many chemical properties of compounds. Hint: Simply search for the name of the compound and the property you are looking for, such as benzene and "boiling point." Notable titles include:
Kinetics data is difficult to find because each set of reaction conditions is unique. Searching the literature is a good way to find this data, otherwise there area a few databases that might help.
Other Resources for Chemical and Thermophysical Properties
These are other individual titles you might consider consulting if Knovel and CRCnetBASE do not have what you need. There are also a number of print resources within the Chemistry Library that you might find useful, including the NIST-JANAF tables (Ref. 541.360212 J251 1998.) and the DECHEMA Chemistry Data Series.

Perry's Chemical Engineers' Handbook
The Marriott Library has online access to Perry's 8th edition.
CRCnetBASE is a collection similar to Knovel, that has titles related to chemistry and chemical engineering. It also contains a number of handbooks related to data on polymers. You can search across the entire collection or connect directly to specific titles of interest below:
