HH-5 毛细管柱测定3-甲硫基丙醛

固定相：5%苯基-甲基聚硅氧烷
规格：30m*0.53mm*1.20um
型号：HH-5

应用：GB 28341-2012 食品安家标准 食品添加剂 3-甲硫基丙醛

4-硫代戊醛，化学式为C4H8OS。有恶臭的液体，用作食用香精、GB 2760--1996规定为允许使用的食品用香料。

由丙烯醛与甲硫醇经加成反应而得。将丙烯醛和甲酸加入反应锅中，搅拌下加入乙酸酮，加热30-40℃，通Chemicalbook入经冷却、酸洗脱水的甲硫醇，反应液相对密度达到1.060-1.074（20℃），即得3-甲硫基丙醛。

Determination of 3-methylthiopropionaldehyde by capillary column
Determination of 3-methylthiopropanal by capillary column Details:

Stationary phase: 5% phenyl-methyl polysiloxane
Specification: 30m * 0.53mm * 1.20um
Model: HH-5

Application: GB 28341-2012 National Food Safety Standard Food Additive 3-Methylthiopropanal

4-thiovaleraldehyde, with the chemical formula C4H8OS. A foul-smelling liquid, used as a food flavor, GB 2760-1996 stipulates that food spices are allowed to be used.

Derived from acrolein and methyl mercaptan through addition reaction. Add acrolein and formic acid to the reaction pot, add ketoacetate with stirring, heat to 30-40 ° C, and pass into the Chemicalbook with cooled, acid-eluting methyl mercaptan, until the relative density of the reaction solution reaches 1.060-1.074 (20 ° C ) To obtain 3-methylthiopropanal.
Tengzhou Haohan Instrument Technology Service Co., Ltd., sampling HH-5 capillary chromatography column, FID detector, area normalization method for the determination of food additive 3-methylthiopropionaldehyde, the results are accurate and reliable.
