With carbon dioxide; ammonia; potassium hydroxide; zinc(II) oxide In water at 50 - 100℃; | 2 Prepare 600 grams of solution A as in Example 1 with 9.56% zinc. Add 243 grams of 2-mercaptobenzothiazole with acid value of 327 mg of KOH per gram and melting point of about 180° C. to the solution. Stir and warm the solution to 50° C. for one hour. The pH of this solution is measured at 10.67. Heat the solution to boil off the ammonia and carbon dioxide. The solution boils at about 60° C. to 90° C. When all the ammonia is boiled out the temperature rises to 100° C. and the pH drops to 8.57. Cool the mixture to 25° C. Filter the mixture and dry the white precipitate at 150° C. for 6 hours, and then and mill it to obtain zinc 2-mercaptobenzothiazole (ZMBT), sample No. ZMBT-A, with the following properties: Commercial ZMBT A ZMBT Zinc (wt. %) 18.56 17.42 Acid Value (mg KOH/g) 52.07 50 Melting point (° C.) 330 (dec) 330 (dec) pH 7.57 7.88 Bulk density (g/cm3) 0.58 0.6 Residue on 150 Mesh Sieve 0.1 2.4 (wt. %) This material has comparable characteristics to commercial zinc 2-mercaptobenzothiazole obtained from Master Glove (commercial ZMBT). |

99.5% | In water Milling; Green chemistry; | 2 Example 2 In a 45 mL ball mill reactor 8 diameter 2mm chrome steel ball were placed, 2-mercaptobenzothiazole (2.67 g, 16 mmol) was added sequentially, zinc sulfate (1.61 g, 10 mmol), water (lmL), feeding finished, the reactor was sealed and placed in a ball mill at a rotational speed of 300 revolutions per minute for 5 minutes and a pause of 30 seconds for one cycle. After four cycles, TLC tracking indicated the consumption of 2-mercaptobenzothiazole was complete and the reaction mixture was washed with water (5 mL X3)Filtration and drying the filter cake yielded 3.17 g of the solid product in 99.5% yield. X-ray powder diffraction of the sample is shown in Fig. 2. The interplanar spacing d = 13.2999, 9.6207, 8.9702, 7.3719, 6.5067, 5.6519, 5.2328 Am belongs to the characteristic peak of zinc-2-mercaptobenzothiazole. |
