Embodiment 1
[0020] Example 1: The extraction method of extracting inositol calcium magnesium hexaphosphate and co-producing nicotine from tobacco waste, the specific operation is as follows:
[0021] (1) Collect the tobacco root after the tobacco farmers harvest the tobacco leaves and crush it to a length of less than 3 mm and a diameter of less than 1 mm;
[0022] (2) Take 100kg of tobacco root fragments, put them in the soaking tank, add 300kg of hot water at 65°C, adjust the pH to 5.0 with industrial sulfuric acid with a concentration of 90% by mass, keep the soaking temperature at 65°C, and add acid to maintain The soaking pH is 5.0, stir once every 10 minutes, soak for 3 hours, then pass in water vapor, raise the soaking temperature to 85°C and keep it constant, keep the pH 5.0, extract for 1 hour, filter, and the filtrate is used as raw material; the filter residue is used as raw material Repeat the above operation steps to perform a second extraction, combine the two extraction fi...
Embodiment 2
[0029] Example 2: The extraction method of extracting inositol calcium magnesium hexaphosphate and co-producing nicotine from tobacco waste, the specific operation is as follows:
[0030] (1) Collect the tobacco stalks after the tobacco farmers harvest the tobacco leaves and crush them to the tobacco stalk fragments with a length of less than 3 mm and a diameter of less than 1 mm;
[0031] (2) Take 100kg of tobacco stalk scraps, put them in the soaking tank, add 350kg of hot water at 70°C, adjust the pH to 5.2 with 90% industrial sulfuric acid, keep the soaking temperature at 70°C, and add acid to keep the soaking pH at 5.2 , stirred once every 10 minutes, soaked for 3 hours, then introduced water vapor, raised the soaking temperature to 85°C and kept it constant, kept the pH 5.2, extracted for 1 hour, filtered, and the filtrate was used for later use; repeat the above steps with the filter residue as raw material , carry out secondary extraction, combine the two extraction ...
Embodiment 3
[0038] Example 3: The extraction method of extracting inositol calcium magnesium hexaphosphate and co-producing nicotine from tobacco waste, the specific operation is as follows:
[0039] (1) Collect the remaining tobacco leaves after the tobacco farmers harvest the tobacco leaves and crush them into pieces of tobacco leaves less than 3 mm in length;
[0040] (2) Take 150kg of tobacco leaf fragments, put them in the soaking tank, add 500kg of hot water at 65°C, adjust the pH to 6.0 with 90% industrial sulfuric acid, keep the soaking temperature at 65°C, add acid to keep the soaking pH at 6.0, Stir once every 15 minutes, soak for 3.5 hours, then pass in steam, raise the soaking temperature to 90°C and keep it constant, keep the pH at 6.0, extract for 1.5 hours, filter, and use the filtrate for later use; repeat the above steps with the filter residue as raw material , carry out secondary extraction, combine the two extraction filtrates, and filter residue for later use; fully...
