Embodiment 1

[0034] A preparation method of 12 kinds of vitamin raw materials thiamine pyrophosphate tetrahydrate for injection, characterized in that the preparation method comprises the following steps:

[0035] (1) Soak 2kg of Amberlite resin with 0.1mol / L HCl of 3.3L for 0.5h, filter, then repeatedly wash twice with 0.1mol / L HCl, filter, and dry to obtain acid-treated Amberlite resin;

[0036] (2) Soak the Amberlite resin that the acid treatment of step (1) gained is crossed 0.5h with 5% NaOH solution, filter, wash 2 times with 5% NaOH solution then, filter, wash the Amberlite resin that alkali treatment is crossed with distilled water, obtain Activated Amberlite resin; store the activated resin in a -4°C environment for future use.

[0037] (3) The activated 2kg Amberlite resin obtained in step (2) is placed in a container, then an appropriate amount of distilled water is added, vigorously stirred to drive out the air bubbles as much as possible, then the column packing takes by weigh...

Embodiment 2

[0040] This embodiment relates to the quality detection of thiamine pyrophosphate tetrahydrate obtained in embodiment 1. The test results are shown in the table below:

Abstract

The invention discloses a preparation method of thiamine pyrophosphate tetrahydrate in 12 vitamin raw materials for injection. The preparation method comprises the following steps: (1) acidizing of Amberlite resin to obtain acid-treated Amberlite resin; (2) activating the acid-treated Amberlite resin to obtain activated Amberlite resin; (3) packing the activated Amberlite resin; preparing a thiamine pyrophosphate hydrochloride solution, loading, reducing pressure and chromatographing by using distilled water as a mobile phase, and post-treating the eluate to obtain a crude product of thiaminepyrophosphate tetrahydrate; (4) dissolving the crude product of thiamine pyrophosphate tetrahydrate in water to form a thiamine pyrophosphate tetrahydrate solution; adding anhydrous ethanol to the solution until a turbid phenomenon appears, heating to complete dissolution, still standing, and filtering to obtain the thiamine pyrophosphate tetrahydrate.
