Description
Technical field
The utility model relates to salicylonitrile production field, is specifically related to a kind of for salicylonitrile production rectifying column.
Background technology
Salicylonitrile product is the key intermediate of synthesis treatment cardiovascular and cerebrovascular diseases medicament bunitrolol and agriculture chemicals fungicide Fluoxastrobin, and cardiovascular and cerebrovascular diseases are number one killer of harm humans health.2003, about 1,670 ten thousand people of cardiovascular and cerebrovascular diseases were died from the whole world, account for 29.2% of total death toll, all the time, it is believed that cardiovascular and cerebrovascular diseases are high at western countries' incidence of disease, and still not general in the population of Asia.And the first tenday period of a month September in this year, international research personnel propose up-to-date evidence in Beijing, by showing the research of 500,000 Asia populations: cardiovascular and cerebrovascular disease is just starting to form China and the health of other Asian countries and wealth to have a strong impact on, and many Asians could just be subject to the threat of heart disease and headstroke in the prime of life! Many than west youth of the age that Asian suffers from a heart complaint.At present, China has patients with hypertension 1.3 hundred million people, about 6,000 ten thousand people of dyslipidemia, about 2.4 hundred million people of overweight, obesity about 7,000 ten thousand people, the incidence of disease of China's cerebral apoplexy is higher, it is Hesperian 4 times, patients with cerebral apoplexy about 7,000,000 people of the existing work of China, wherein 75% disability in various degree, 70% severe disables.Every year because cardiovascular and cerebrovascular diseases death toll is 2,600,000 people, (wherein, dead 1,500,000 people of headstroke, coronary heart disease death 1,100,000 people), account for 41% of total death toll, every day, nearly 7000 people died from cardiovascular and cerebrovascular diseases, average dead 300 people per hour.According to first-aid centre of Beijing statistics in 2003, what Beijing died from cardiovascular and cerebrovascular diseases accounts for 51% of general mortality rate, not long ago a investigation finds, the incidence of disease of China not only hypertension, coronary heart disease, headstroke is increasing, and age of onset in advance, present rejuvenation trend, crowd's incidence of disease of less than 40 years old accounts for 20%, the minimum age record of coronary heart disease is 16 years old, and the minimal ages record dying from cerebral hemorrhage is 18 years old.To this, expert call: should take an immediate action and implement precautionary measures, reduces the incidence of disease of cardiovascular and cerebrovascular diseases, reduce the death rate and disability rate extremely urgent.
Produce salicylonitrile time can adopt ortho-xylene and water sample acid amides be raw material carry out reaction generation, phosgene is passed into during production, the product crystallization finally generated, centrifugation, centrifuge mother liquor is reclaimed dimethylbenzene through rectifying still (R-106, R-107) rectifying, distillation control temperature is 115 DEG C, pressure is normal pressure, could reclaim, existing rectifier unit recovering effect is very poor, and containing a lot of impurity, easily has gas to be taken out of by part material when reclaiming simultaneously, and waste resource, waste space during recovery.
