Description
Известен способ получени нитрата 3-«итробутанола-2 обработкой 2-бром- или A known method for producing nitrate 3- "itrobutanol-2 by treatment with 2-bromo- or
2-йоднитробутана серно-азотной кислотной смесью. 2-iodine nitroxide sulfuric acid mixture.
Однако исходные бром- йодпроизводные - труднодоступное сырье:However, the initial bromine-iodine derivatives are hard-to-reach raw materials:
С целью упрощени способа предложено получать нитрат З-нитробутанола-2 в результате обработки хлорбутана смесью кон центрированных серной и азотной кислот. In order to simplify the process, it has been proposed to prepare nitrate of 3-nitrobutanol-2 as a result of treating chlorbutane with a mixture of concentrated sulfuric and nitric acids.
П р и М е р. В трехгорлую колбу, снйбженную механической мешалкой, обратным холодильником, термометром и капельной воронкой, помещают серно-азотную смесь, . приготовленную смешением 9О г технической 98%-ной азотной кислоты и 1ОО г 94%-ной серной кислоты, и при температуре 18-20°С добавл ют 15 Г2-хлорбуга на . Состав при этой температуре перемешивают в течение 2 час, затем выливают в смесь воды со льдом п экстрагируют эфиром или хлороформом. Экстракт промы- BaiOT последовательно водой,. 2%-ным растi BOpoM соды, снова водой и высушивают над PRI and MER. In a three-necked flask, snibzhzhennu mechanical stirrer, reflux condenser, thermometer and addition funnel, put the sulfur-nitrogen mixture,. prepared by mixing 9O g of technical 98% nitric acid and 1OO g of 94% sulfuric acid, and 15 G2-chlorbuga are added at a temperature of 18–20 ° C. The composition at this temperature is stirred for 2 hours, then poured into a mixture of ice water and extracted with ether or chloroform. The extract is washed with BaiOT water. 2% grow BOpoM soda, again with water and dry over
безводным сульфатом натри . Растворитель отгон ют н оставшийс в колбе нитрат 3-нитробутанола-2 очищают перегонкой в вакууме.anhydrous sodium sulfate. The solvent is distilled off and the nitrate 3-nitrobutanol-2 remaining in the flask is purified by distillation in vacuo.
