Embodiment 1

[0025] The preparation method of the anthrone glucosamine Schiff base of the present embodiment is to dissolve 1.9422g (10mmol) of anthrone in 120ml of anhydrous methanol, add 2.152g (10mmol) of D-glucosamine hydrochloride and 0.19g of Triethylamine was heated to 65°C, refluxed for 6 hours, then cooled to room temperature, filtered, and light yellow precipitate was collected, washed with water, methanol, and anhydrous ether for several times, and vacuum-dried to obtain the product. The yield was 73.4%. The reaction formula is as follows:

[0026] .

[0027] The infrared spectrum of the product is shown in figure 1 shown. from figure 1 It can be seen in 3400cm -1 The broad peak at is the peak of the hydroxyl group and the generated hydrogen bond, which is a typical polyhydric feature of sugar. 3083cm -1 The small peak at is the C-H stretching vibration peak on the polyaryl ring, and the 2900cm -1 Nearby is the C-H stretching vibration peak on the sugar ring. 1642 and...

Embodiment 2

[0030] The preparation method of the anthrone glucosamine Schiff base of the present embodiment is to dissolve 1.9422g (10mmol) of anthrone in 180ml of anhydrous methanol, add 4.304g (20mmol) of D-glucosamine hydrochloride and 0.22g of Triethylamine, heated to 63°C, reflux reaction for 7 hours, then cooled to room temperature, filtered, collected light yellow precipitate, washed with water, methanol, and anhydrous ether several times, and vacuum dried to obtain the product anthrone glucosamine Schiff alkali. The yield was 73.1%.

Embodiment 3

[0032] The preparation method of the anthrone glucosamine Schiff base of the present embodiment is to dissolve 1.9422g (10mmol) of anthrone in 150ml of anhydrous methanol, add 3.228g (15mmol) of D-glucosamine hydrochloride and 0.16g of Triethylamine, heated to 68°C, reflux reaction for 5.5 hours, then cooled to room temperature, filtered, collected light yellow precipitate, washed with water, methanol, and anhydrous ether several times, and vacuum dried to obtain the product anthrone glucosamine Schiff alkali. The yield was 71.2%.

Abstract

The invention relates to a detection method of sodium saccharin; anthrone glucosamine Schiff base having a structure as shown in a formula I is taken as a fluorescent chromogenic agent of the sodium saccharin. The detection method of the sodium saccharin is convenient and easy to implement, high in sensitivity and strong in resistance to interference, and can be used for rapidly detecting the sodium saccharin.

Description

technical field [0001] The invention relates to a method for detecting sodium saccharin by using fluorescence color development, and belongs to the technical field of detection. Background technique [0002] Sodium saccharin is a commonly used food additive in the process of food production, but the phenomenon of abuse in the actual production process is very serious. Compared with developed countries, the amount of saccharin used in my country exceeds the normal amount by 14 times (Jiang Xueya, Yuan Tingting, Huang Yiping, Zheng Yuxuan, Technical Discussion on the Detection of Sodium Saccharin in Jujube, "China Food Additives", Issue 01, 2016, 147-151). Sodium saccharin was discovered by American scientists in 1878. It is called the sodium salt of o-benzoylsulfonimide. It is easily soluble in water. Its one-hundred-thousandth aqueous solution has obvious sweetness. bitterness. Sodium saccharin has no nutritional value. On the contrary, when more sodium saccharin is taken,...
