1. prepare sufficient quantities of

1. prepare sufficient quantities of water, refrigerator freezer, and set aside. The drug, pour the grains into stand-up 500 ml flask, then add alcohol, until the grains surface 2-4 cm higher ethanol, ethanol added after, grains were sunk, it's easy to tell,
2. place the flask into electric sets, good mixer, leaf in stirring, stirring drag a centimeter or so, starting stirring, not too fast, speed is good. After heating, heated to boiling liquids, temperature is not too high, temperature should not exceed 70 degrees. Stir until the liquid completely dissolve pseudoephedrine, almost half an hour or so, stop heating. Sealed 5-8 hours.
3. When you save the time, filter out residue, such as difficult to filter, select the filter, with a very fine and very fine cloth. Pouring liquid into beaker filtered, heated slightly. Take out the ice water will be ready, look at how many ml of liquid, such as 200 ml of liquid, add 200 ml of water, then rapid stirring with a glass rod and heat while stirring, slowly, there are impurities in the liquid precipitation. Filter out impurities, transparent color like wine liquid left.
3. next distillation off ethanol, zhiqian we added of is 200 ml ethanol, plus ice water, altogether 400 ml, will beaker put into electric sets heating, temperature control good, don't let liquid boiling on line, ethanol of boiling point than water low, ethanol will first was distillation out,, beaker in of liquid left 200 when, by in smell smell, if no alcohol of taste, that proved ethanol was distillation off has, distillation good Hou, placed cooling, pumping filter a again,
4 then to liquid pour sodium hydroxide, added hydrogen oxidation sodium of when to note, put of when to slow, mixing speed to fast, until sodium hydroxide all dissolved, then with glass rod stick points liquid, coated in PH strips Shang, PH strips color, according to color control PH try tray Shang of than color Board, until PH=13, at liquid has sediment produced, then pumping filter, alkaline of pseudo ephedrine all in filter paper Shang, out, roast dry,
5 1:1 alcohol dissolves, then add hydrochloric acid, plus side measuring liquid PH value until the acid PH=3. And then distilling alcohol, steamed for about 3 left 1 time, stopping distillation, cooling. Waiting for the Crystal, the Crystal is the element we want, after all the crystals filter out Crystal, baking dry and left those of ethanol, heat concentrated, cooling and crystallizing

First contac with toluene, ethanol were mixed, and then neutralized with sodium hydroxide to debug, followed by distillation, will be white or light yellow powder articles, mixing after addition of diethyl ether, neutralized with sodium hydroxide debugging again, then filtered and the residue filtered, and then subjected to distillation (liquid color yellow), you can get back, pale yellow powder particles, and then use the ether purification filter, you can get a white particulate matter (powdered), can be obtained as white crystals after natural dried 1. Prepare a sufficient amount of water, fridge freezer and set aside. The drug, the drug granules poured into 500 ml single-necked flask, and then fill it with ethanol, drug particle surface until the ethanol was up 2-4 centimeters, then ethanol added, prills is sink to the bottom, it is easy to distinguish, 2 . The flask into the heating units, stand a good mixer, the mixing leaves into them, stirring the leaves about one centimeter from the bottom of the flask, starting stirring, not too fast, the speed is good. After heating, the liquid was heated to boiling temperature not too high, the temperature should not exceed 70 degrees. Stirring until the liquid is completely dissolved straight pseudoephedrine, almost half an hour or so, stop heating. Sealed 5-8 hours. 3 .. Save time to time, pumping filtered dregs, such as the difficulty optional suction filtered, washed with very thin cloth can be. The filter out of the liquid poured into a beaker, a little heated. The prepared ice out, look how many ml of liquid, for example, 200 ml of liquid, then add 200 ml of ice water, then quickly stirred with a glass rod, while heating with stirring, slowly, liquid there impurity precipitation. Pumping filtered impurities, remaining transparent wine-colored liquid. 3. Next, ethanol was distilled off, before we added 200 ml of ethanol, combined with ice water, a total of 400 ml, the beaker was placed in an electric heating jacket, temperature control is good, do not let the liquid boil on the line, the boiling point of ethanol is lower than that of water ethanol can be distilled off first, and so beaker of liquid left 200 time, go by smell, if there is no taste of alcohol, that proof ethanol is distilled off, the distillation is completed, allowed to cool, suction again, then go 4 pour liquid sodium hydroxide, sodium hydroxide plus time to pay attention, to put the time to slow faster stirring until completely dissolved sodium hydroxide and then with a glass rod sticking point of the liquid, painted on the PH test paper, PH test strips change color , according to the color swatches PH test than the control on the tray until PH = 13, this time the liquid has precipitates, then filtration, pseudoephedrine basic all on the filter, remove, dried, 5 with 1 more than 1 ethanol solution, then a solution of hydrochloric acid, while adding value side PH Measuring liquid until acidic PH = 3. Then distilled ethanol, and other leftover steamed about 3 minutes a time, stop distillation, to take up the cooling. Wait crystal, the crystal is that we want prime, and after all the crystallization of the crystals were filtered out, cold roast spare, those leftover ethanol, concentrated by heating it, cooling, and again with the crystal precipitation
