Abstract
Изобретение относитс к органическому синтезу, в частности, к получению фенола . Цель - увеличение выхода целевого продукта . Получение ведут окислением бензола оксидом азота при 350 - 400°С в присутствии катализатора. В качестве последнего используют цеолит типа пентасил с мольным отношением 5Ю2/А 20з в интервале 40 - 100. Способ позвол ет повысить выход целевого продукта на 1,3 - 3,3% и упростить технологию за счет снижени температуры процесса на 100%. 2 табл.The invention relates to organic synthesis, in particular to the production of phenol. The goal is to increase the yield of the target product. The preparation is carried out by oxidation of benzene with nitric oxide at 350-400 ° C in the presence of a catalyst. As the latter, a pentasil-type zeolite with a molar ratio of 5X2 / A 20g in the range of 40-100 is used. The method allows to increase the yield of the target product by 1.3-3.3% and to simplify the technology by reducing the process temperature by 100%. 2 tab.
Description
Изобретение относитс к способу получени фенола который вл етс ценным многотоннажным продуктом, дл производ ства фенольных смол, синтеза капролакта- мэ, синтеза адипиновой кислоты.The invention relates to a method for producing phenol, which is a valuable multi-ton product, for the production of phenolic resins, the synthesis of caprolactame, and the synthesis of adipic acid.
Цель изобретени - увеличение выхода целевого продукта. The purpose of the invention is to increase the yield of the target product.
Пример 1. Пентасил с отношением. 5Ю2/А120з.- 100, загружают в кварцевый реактор с внутренним диаметром 7 мм, Объем катализатора 2 см3, катализатор беретс в виде фракции 0,5 - 1 мм. На катализатор, нагретый до заданной температуры, подают со скоростью 60 см /мин реакционную смесь следующего состава (моль. %): бензол - 4,8, оксид азота (1) - 19,5, остальное гелий или иной инертный газ, например, азот. С помощью газового хроматографического анализа определ етс состав реакционной смеси до и после реактора, на основании чего рассчитываетс степень превращени бензола, селективность по фенолу и выход фенола. Помимо CeHsOH и С02, других угле- водородсодержащих соединений, а в том числе малеионового ангидрида и СО, средиExample 1. Pentasil with attitude. 5U2 / A120z.- 100, loaded into a quartz reactor with an inner diameter of 7 mm, the volume of the catalyst is 2 cm3, the catalyst is taken in the form of a fraction of 0.5-1 mm. A reaction mixture of the following composition (mol.%) Is supplied to a catalyst heated to a predetermined temperature at a speed of 60 cm / min: benzene - 4.8, nitric oxide (1) - 19.5, the rest is helium or another inert gas, for example, nitrogen. Using gas chromatographic analysis, the composition of the reaction mixture before and after the reactor is determined, based on which the degree of benzene conversion, phenol selectivity and phenol yield are calculated. In addition to CeHsOH and CO2, other hydrocarbon-containing compounds, including maleic anhydride and CO, among

При м е р ы 2 - 14. Реакцию ведут, аналогично примеру 1. Примен емый катализатор , температура реакции и полученные результаты представлены в табл. 1 и 2. Табл. 2 показывает неэффективность использовани цеолитов других типов, кроме предложенного, в данном способе.Examples 2 to 14. The reaction is carried out, analogously to example 1. The catalyst used, the reaction temperature and the results obtained are presented in table. 1 and 2. Tab. 2 shows the inefficiency of using zeolites of other types than those proposed in this method.
Данный способ позвол ет повысить выход целевого продукта на 1,3 - 3,3%, в сравнении с прототипом и упростить технологию за счет снижени температуры процесса на 100% (в сравнении с прототипом ). Изменение мольного соотношени бензол: оксид азота в интервале 1 : 1,7 - 5,6 не вли ет на достижение поставленной цели.This method allows to increase the yield of the target product by 1.3 - 3.3%, in comparison with the prototype and to simplify the technology by reducing the process temperature by 100% (in comparison with the prototype). A change in the molar ratio of benzene: nitric oxide in the range of 1: 1.7-5.6 does not affect the achievement of the goal.
