\n Store in a cool, dry, well-ventilated non-combustible warehouse. Keep away from fire and heat sources. The warehouse temperature should not exceed 28\u2103.The packaging must be sealed and must not come into contact with air. Keep away from light. Not suitable for large quantities or long-term storage. It should be stored separately from acids, flammables, combustibles, oxidants, oxygen, compressed air, etc. The lighting, ventilation and other facilities in the storage room should be explosion-proof, and the switches should be located outside the warehouse. Equipped with the appropriate variety and quantity of fire equipment. Fire and explosion prevention technical measures must be taken during tank storage. It is prohibited to use mechanical equipment and tools that are prone to sparks. When handling, load and unload with care to prevent damage to packaging and containers. Smoking, drinking, and eating are not allowed at the operation site.\n <\/p>\n
\n Use carbide tools to cut single crystal magnesium flakes with a purity of 99.999%, wash them several times with ether treated with lithium aluminum tetrahydride, and add a dry ice-acetone condenser tube. And in the reaction bottle directly connected to the ether distillation device. The device is repeatedly baked with gas lamps and filled with high-purity nitrogen several times. Add dry ice to the condenser tube, evaporate 50 mL of ether directly into the flask, and then introduce a small amount of ethyl bromide from the side tube installed near the bottom of the condenser tube. Bubbles are released and heat is released, proving that the reaction has begun. Thereafter, continue to pass in methyl bromide and steam into ether. Keep methyl bromide and ether at reflux without heating until the magnesium metal reacts completely. During this period, it is appropriate to keep the ether solution at about 300 mL. Remove the flask in the nitrogen flow and put it in the operating box with a stopper, filter it into the flask with a glass sand funnel, and cover it with a tetrafluoroethylene piston. A colorless and transparent methylmagnesium bromide solution was obtained. The ratio of the analytical values \u200b\u200bof C:Mg:Br is 1.00:1.03:0.99. <\/p>\n<\/span><\/span>\n <\/p>\nPurpose<\/h2>\n\n for organic synthesis\n <\/p>\n extended-reading:https:\/\/www.bdmaee.net\/dibutylstanniumdichloride\/<\/a><\/br>extended-reading:https:\/\/www.cyclohexylamine.net\/tetrachloroethylene-perchloroethylene-cas127-18-4\/<\/a><\/br>extended-reading:https:\/\/www.bdmaee.net\/lupragen-n400-catalyst-trimethylhydroxyethyl-ethylene-diamine-basf\/<\/a><\/br>extended-reading:https:\/\/www.bdmaee.net\/jeffcat-zr-50-catalyst-cas67151-63-7-huntsman\/<\/a><\/br>extended-reading:https:\/\/www.bdmaee.net\/wp-content\/uploads\/2022\/08\/115-10.jpg<\/a><\/br>extended-reading:https:\/\/www.bdmaee.net\/cas-108-01-0\/<\/a><\/br>extended-reading:https:\/\/www.bdmaee.net\/wp-content\/uploads\/2022\/08\/33-12.jpg<\/a><\/br>extended-reading:https:\/\/www.bdmaee.net\/wp-content\/uploads\/2022\/08\/59.jpg<\/a><\/br>extended-reading:https:\/\/www.newtopchem.com\/archives\/43944<\/a><\/br>extended-reading:https:\/\/www.bdmaee.net\/nt-cat-pc46-catalyst-cas127-08-2-newtopchem\/<\/a><\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"Structural formula Business number 01J3 Molecular formu…<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":49243,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[6],"tags":[15424],"gt_translate_keys":[{"key":"link","format":"url"}],"_links":{"self":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts\/49244"}],"collection":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/comments?post=49244"}],"version-history":[{"count":0,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts\/49244\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/media\/49243"}],"wp:attachment":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/media?parent=49244"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/categories?post=49244"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/tags?post=49244"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
