4-メチルシクロヘキサン-1,2-ジカルボン酸 無水物 化学特性,用途語,生産方法
外観
無色～ほとんど無色透明液体
説明
Methylhexahydrophthalic anhydride (MHHP A) is an
epoxy hardener, irritant to skin and mucus membranes.
It is included in non-diglycidyl-ether-of-bisphenol-
A epoxy resins. It can induce both allergic
contact dermatitis and immunologic contact urticaria.
MHHP A is structurally close to methyltetrahydrophthalic
anhydride (MTHP A), which can also cause
sensitization.
化学的特性
Hexahydro-4-methylphthalic anhydride has a melting point of 29 °C, so it
is a liquid at room temperature. It has a boiling point of 120 °C and
at 25 °C its density is 1.162 g/mL.
使用
Hexahydro-4-methylphthalic anhydride, mixture of?cis?and?trans may be used as an analytical standard for the determination of the analyte in human biological samples by gas chromatography-mass spectrometry (GC-MS).
一般的な説明
Methylhexahydrophthalic anhydride, a congener of phthalic anhydride, is utilized in the production of plastics, paints, and electronic components. It can potentially result in allergenic effects on humans upon exposure and cause immunological reactions.

合成
5-methyl-3a,4,7,7a-tetrahydroisobenzofuran-1,3-dione could used as a starting material to synthesize Hexahydro-4-methylphthalic anhydride. The byproducts include 5-methylisobenzofuran-1,3-dione, 5-methyl-4,5,6,7-tetrahydroisobenzofuran-1,3-dione, and 6-methyl-3a,4,5,7a-tetrahydroisobenzofuran-1,3-dione.
