Embodiment 1
[0091] Embodiment 1: the preparation of HPB-1
[0092] Sodium tungstate dihydrate (600 grams, 1.82mol), sodium dihydrogen phosphate (120 grams, 0.86mol) were dissolved in 2000 grams of distilled water, titanium tetrachloride (61 grams, 0.32mol) was added dropwise, back distillation 20 minutes, After filtration, 600 g of solid KCl was added to the filtrate to obtain a white precipitate. The precipitate was recrystallized with 500 g of hot water to give solid K 7 PTi 2 W 10 o 40 ·5H 2 O66g, K 7 PTi 2 W 10 o 40 ·5H 2 Dissolve O66g in 500g of water, add 11g of hydroxylamine hydrochloride and stir, then add 11g of lanthanum chloride, stir at 40-80°C for 2-8 hours, a few days later a colorless crystal K will precipitate 4 (H 2 O) 4 [K 3.5 La 0.5 (H 2 O) 8 ClPTi 2 W 10 o 40 ]·NH 2 Oh. The molecular structure diagram is attached figure 1 . The HPB-1 production flow chart is attached figure 2 .
Embodiment 2
[0093] Embodiment 2: the preparation of HPB-2
[0094] Prepare K by the method of above-mentioned embodiment 1 7 PTi 2 W 10 o 40 ·5H 2 O, K 7 PTi 2 W 10 o 40 ·5H 2 Dissolve O66 g in 500 g of water, add 9 g of hydrazine hydrate and stir, then add 12 g of neodymium chloride, and stir at 40-80°C for 2-8 hours. After a few days, purple crystals of K were precipitated 4 (H 2 O) 4 [K 3.5 Nd 0.5 (H 2 O) 8 ClPTi 2 W 10 o 40 ]·NH 2 NH 2 (HPB-2) 80g.
[0095] The preparation method of the above examples 1 and 2 can be arbitrarily enlarged or reduced according to the mass ratio of the formula.
[0096] The synthesized HPB-1, HPB-2 and excipients can be made into capsules at a weight ratio of 1:3. According to the ratio of its weight to the excipient of 1:3, it is made into a compressed tablet. Add water for injection according to the conventional injection preparation method, filter, potting and sterilize to make injection.
