Phthalic Anhydride 99.9% Purity CAS 85-44-9
Molecular Formula: C8H4O3.Molecular Weight: 148.116CAS No.:85-44-9Phthalic anhydride, abbreviated as phthalic anhydride, is a cyclic acid anhydride formed bydehydration of phthalic acid molecules, Phthalic anhydride, a white solid, is an importantraw material in the chemical industry, especially for the manufacture of plasticizersPhthalic anhydride can be used instead of phthalic acid, mainly reacting with monoalcohols to form esters, such as dibutyl phthalate, dioctyl phthalate.
**Phthalic Anhydride **Specification:
| Items | Specification |
| Purity %(M/M) | ≥99.5 |
| Molten Color | ≤20 |
| Solidification Point (°C) | ≥130.5 |
| Thermally stable chroma (%) | ≤50 |
| Free acid (%) | ≤0.2 |
| Sulphuric acid color | ≤40 |
**Packing：25kg/500/1000kg nylon bag
Applications :
1.Phthalic anhydride is one of the most important organic chemical raw materials, and its main derivatives are dibutyl phthalate; Dioctyl ester and diisobutyl ester are used as plasticizers for
PVC, etc; It can also be used to produce unsaturated polyester resin; Alkyd resin; Dyes and pigments; Various paints; Food additives; Phenolphthalein, a laxative in medicine; Imiphos in
pesticides; Clomazone and saccharin sodium, etc.
2.Phthalic anhydride is used as curing agent of epoxy resin
