Toxicity grade

GRAS(FEMA)

Usage restriction

FEMA(mg/kg):drinks , cold drinks 0.13; sweets 0.03~0.13; bakery  products 0.03

Chemical Properties

Slightly yellow transparent liquid, b.p.72~73℃/1.5kpa(or 187℃),n20D 1.5307,density 1.1070, Soluble in benzene, toluene, carbon tetrachloride, insoluble in water.

Usage

It meets GB 2760—1996 standards of edible spices. It is the intermediate of allethrin and prallethrin and used as tobacco essence.

Production

5-Methyl furfural is produced by distillation of various kinds of methylpentose with acid together. The production process was as the following.    2-methylfuran and N, N-dimethyl formamide were firstly added to a 3-neck flask. Then, phosphorus oxychloride was added slowly to the flask and the reaction was kept for 1~2h at low temperature. The reagent was dumped into the water, neutralized by Na2CO3. By separating the oil layer, extracting the water layer with solvent, merging of the organic phase and the oil layer, drying, desolvation by distillation, reduced pressure distillation, we get the final product.

Description

5-Methylfurfural has a sweet, spicy, warm odor with a sweet caramel-like flavor. May be prepared from sucrose with HCL, followed by treating with stannous chloride; from various methylpentoses by distillation with acid.
