二异丙基偶氮羧酸盐 - Reference Information
| product description | diisopropyl azodicarboxylate (English Diisopropyl azodicarboxylate;Diisopropyl azodiformate referred to as DIAD; The foaming agent DIPA) belongs to diisopropyl azo hydroxy salt. It is an orange-red transparent oily liquid at room temperature, has a special smell, is soluble in almost all organic solvents and plasticizers, is insoluble in water, is soluble in general plasticizers, has good mutual solubility with plastics, and has good thermal stability. Stable storage. The decomposition product is colorless, non-toxic, non-polluting, non-spraying frost, and no odor. High gas volume can be obtained in the range of 40~120 ℃. It is a liquid foaming agent for vinyl resin and can be used to make light-colored vinyl foam. With uniform microporous structure, closed-cell or open-cell foam can be obtained depending on the formula and processing conditions. In addition, it is also used as pharmaceutical intermediates, organic synthesis reagents, etc. |
