Abstract
The invention relates to solid magnesium ethoxide and the manufacturing method. It includes the following steps: using absolute ethyl alcohol and high purity metal magnesium powder as raw material, adding little iodine as catalyst, whisking equal and heating, adding catalyst to take reaction, pouring the solution into drier after reacting, heating to vaporizing alcohol and drying in vacuum to gain solid magnesium ethoxide. The constituents includes: iodine 0.8-1.2, metal magnesium powder 10-16, and absolutely alcohol 300-600. The benefit of the invention is that the content of magnesium ethoxide is high, and other element is low, it could replace liquid magnesium ethoxide to improve reacting yield and product quality, and decrease energy consumption. The vaporized alcohol could be used to compound other products or fully recycled. Thus, the resource would be saved.
Description
Technical field
The present invention relates to a kind of solid magnesium ethoxide and preparation method, belong to metal compound preparation technical field.
Background technology
Solid magnesium ethoxide is the nontoxic medicine source material of a kind of solid magnesium ethoxide and preparation method, indispensable catalyzer series products such as PPA, methoxy Bian pyrimidine main raw material, plastics, spices, essence, makeup, agricultural chemicals.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of solid magnesium ethoxide and preparation method.
The technical solution adopted for the present invention to solve the technical problems is: the operational path of employing is as main raw material with dehydrated alcohol and high-purity magnesium metal powder, add a small amount of iodine again and make catalyzer, the catalyzed reaction of heating after fully stirring, after finishing, reaction injects a solution in the moisture eliminator, heating steams the back to ethanol in vacuum-drying, thereby obtains solid magnesium ethoxide.The part by weight of prescription is:
Iodine 0.8-1.2 metal magnesium powder 10-16 dehydrated alcohol 300-600;
Get metal magnesium powder, dehydrated alcohol and iodine according to the above ratio, fully mix up, begin to heat, temperature is reacted between 60-90 ℃, after reaction finishes, injects a solution in the moisture eliminator, heat ethanol is steamed vacuum-drying again, dryer temperature is about 90-150 ℃, and the ethanol that steams returns use, just obtains solid magnesium ethoxide after drying finishes.
A kind of solid magnesium ethoxide and preparation method comprise the steps:
1, dehydrated alcohol adds metal magnesium powder and adds iodine again, after fully stirring, heats and carries out the synthesis catalytic reaction.
2, after building-up reactions finishes, material is injected in the moisture eliminator, heat and distill vacuum-drying, all other reclaims distillation centrifugal ethanol except that synthetics, and the solution that returns can be used again.
Beneficial effect of the present invention;
The solid magnesium ethoxide major advantage is a magnesium ethylate content height, and it is extremely low that free ethanol and other contain thing, substitutes the liquid magnesium ethylate, can improve reaction yield and quality product, reduces the energy simultaneously.Solid magnesium ethoxide is to intend white, powdery and granular.After building-up reactions finishes, material is injected in the moisture eliminator, heat and distill vacuum-drying, all other reclaims distillation centrifugal ethanol except that synthetics, and the solution that returns can be used again, economizes on resources.
Solid magnesium ethoxide mainly acts on medicine source material, as PPA, methoxy Bian pyrimidine, and catalyzer such as the catalyzer of processing fat and edible oil, plastics catalyzer, spices, essence, makeup, agricultural chemicals.
