hexahydrophthalic anhydride

Cyclohexane-1,2-dicarboxylic acid anhydride , also called hexahydrophthalic anhydride (Hekzahidroftalik anhidrit ) , is a chemical compound from the group of cyclic carboxylic acid anhydrides . There are two carboxylic acid groups in the ortho position on a cyclohexane ring , which together form an anhydride .

 

Extraction and representation 
Cyclohexane-1,2-dicarboxylic acid anhydride is produced by the nuclear hydrogenation of phthalic anhydride . [4] This additional process step is one reason for the higher price compared to the aromatic phthalic anhydride.

 

 

Manufacture of HH-PSA
Usage 
Cyclohexane-1,2-dicarboxylic acid anhydride is used as a monomer in various areas of polymer chemistry . So is z. B. to mention the application as an alternative to phthalic anhydride(Hekzahidroftalik anhidrit ) . What is desired here is better weather resistance, especially against UV light , with high hardness at the same time, which can be achieved by using hexahydrophthalic anhydride(Hekzahidroftalik anhidrit ). [5] Furthermore, with the help of cyclohexane-1,2-dicarboxylic acid anhydride, binders, polyester resins , for paint applications with a significantly lower viscosity compared to those based on isophthalic acidbe generated. This results in a higher processing solids content which is of great interest in times when a lot of attention is paid to environmental protection . [5] Processing solids are understood to be the non-volatile content of a paint system. Since the volatile components are mostly organic solvents ( VOC ), their share should be kept as low as possible. In addition to reducing the absolute amount of paint required or switching to aqueous systems, increasing the processing solids is the best option here.

 

 

In addition to being used as a binder in paints, cyclohexane-1,2-dicarboxylic acid anhydride can also be used as an anhydride hardener for epoxy resins . One application would be casting resin compounds which can cure at room temperature or at elevated temperatures. The higher price compared to phthalic anhydride should also be noted here. [6]

Norway The Norwegian CA supports that hexahydrophthalic anhydride (HHPA, (Hekzahidroftalik anhidrit ) )fulfill the criteria of article 57 f) since evidence exists of serious effects to humans which give rise to equivalent level of concern as CMR substances. HHPA hexahydrophthalic anhydride (Hekzahidroftalik anhidrit ) is harmonized classified as a strong respiratory sensitizer (Resp. Sens. 1) in the CLP regulation and no "safe" no effect level can be derived as regards to the induction of sensitization. During the elicitation phase, the substance may evoke chronic inflammation of the lungs and this can lead to serious and permanent impairment of the lungs. The induced sensitization is irreversible, and exposure of the substance may result in a considerable increased risk of elicitation of respiratory sensitization of affected persons. This may cause limitations of normal working life and could require long term medication. We support that the criteria of article 57 f) is fulfilled and that this substance is of equivalent level of concern as CMR (Cat. 1 or 2) substances. HHPA should be identified as a SVHC substance. Member State
Sweden We agree with the argumentation put forward in the Annex XV dossier and therefore consider hexahydrophthalic anhydride - HHPA hexahydrophthalic anhydride (Hekzahidroftalik anhidrit ) to be a SVHC substance of equivalent level of concern according to Article 57(f). The substance is a classified respiratory sensitizer which may cause severe and irreversible health effects, which clearly affect the quality of life of affected individuals and also high costs for society. It is difficult to establish safe exposure levels for respiratory sensitizers like HHPA hexahydrophthalic anhydride (Hekzahidroftalik anhidrit ) , which is another reason for concern. Further, it is noted that this severe endpoint has not been taken into account by registrants in their chemical safety assessment in the Registration dossier.
