Tin(II) acetate,pure - Reference Information
| Use | hydrocarbon propyl propionate is commonly used as an intermediate in organic synthesis, and can be used in laboratory research and development process. |
| preparation | a process for preparing stannous acetate (propyl hydrocarbon propionate), comprising the following specific steps: (1) weigh stannous oxide, weigh deionized water according to the mass ratio of stannous oxide of 1-2 ∶ 1, and add to the reaction kettle; (2) turn on the stirring, slowly add stannous oxide weighed in step (1); (3) raise the temperature, gradually add glacial acetic acid solution until the temperature rises to 75-85 ℃, stir while adding, complete feeding within 30min; (4) continue to heat up to 95-100 ℃ for 3H; (6) maintain the temperature at 100 ℃, vacuum distillation, to no low boiling material distillation, after the material is white solid, the distillation is stopped; (6) the machine is stopped, the product is taken out, pulverized and dried in an oven at 100 ° C. To obtain the desired stannous acetate (propyl hydrocarbon propionate) product. |
