General description

Predominantly cis 1,2-cyclohexanedicarboxylic anhydride (HHPA) is a cyclic anhydride that can be used for a variety of applications such as: plasticizer, rust inhibitor, and a curing agent for epoxy based resins.

Application

HPPA, in combination with triethaylamine (TEA), can be used as a polymerization initiator in the preparation of polyester based resins. It can also be used as a hardener to cure 1,4-butanediol diglycidyl ether which can be used as an epoxy based system for electronic devices.

The aim of this study was to evaluate the applicability of total plasma protein adducts (TPPA) of 2 sensitizing low-molecular-weight allergens, hexahydrophthalic anhydride (HHPA) and methylhexahydrophthalic anhydride (MHHPA), as biomarkers of long-term exposure. Urine samples from occupationally exposed workers were

For the simulation of therapeutic ultrasound applications, a method including frequency-dependent attenuation effects directly in the time domain is highly desirable. This paper describes an efficient numerical time-domain implementation of the power-law attenuation model presented by Szabo [Szabo, J. Acoust.
