Hexahydrophthalic anhydride Chemical Properties,Uses,Production
Description
Hexahydrophthalic anhydride (HHPA) is widely used for electronics applications, e.g. HHPA cured epoxy resins have excellent dielectric properties, high-temperature stability, and high glass transition temperatures. HHPA is used as a curing agent in adhesive coatings and sealant materials, e.g. for the second-generation two-part epoxy adhesive synthesis. Hexahydrophthalic anhydride is also used in the manufacture of alkyd and polyester resins, insecticides, and rust preventives.

Chemical Properties
White crystalline powder
Uses
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.
Uses
Intermediate for alkyds, plasticizers, insect repellents, and rust inhibitors; hardener in epoxy resins.
Application
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.

Definition
ChEBI: A cyclic dicarboxylic anhydride that is the cyclic anhydride of hexahydrophthalic acid.
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.
Hazard
Toxic by inhalation, strong irritant to eyes and skin.
Flammability and Explosibility
Non flammable
Synthesis
Hexahydrophthalic anhydride is obtained by reacting ciscyclohexane-1, 2-dicarboxylic acid with oxalyl
chloride.Combine
ciscyclohexane-1, 2-dicarboxylic acid (1 mmol, 172 mg) and oxalyl
chloride (1.2 mmol, 152 mg, 0.103 ml) in dry toluene (5 mL) and add a
drop of freshly distilled DMF. Purge the reaction vessel with argon and
heat the reaction under stirring for 3 h. Stop the stirring, decant the
toluene solution and filter. Evaporate the volatiles. Transform into
crystalline form by trituration with diethyl ether. 1H NMR (400 MHz, CDCl3) |? 3.18 - 3.12 (m, 2H 2CH) 1.96 - 1.83 (m, 4H 2CH2) 1.57 - 1.49 (m, 4H 2CH2). HRMS (ESI), calcd for C8H10NaO3 [M+Na]+ 175.0522, found 175.0527; calcd for C9H14NaO4 [M+CH3 OH+Na]+ 209.0784, found 209.0788.
