Description

Настоящее изобретение относится к области химической промышленности, в частности к способу получения жидкости для электронных сигарет.The present invention relates to the field of chemical industry, in particular to a method for producing liquid for electronic cigarettes.

Электронные сигареты, использующие жидкость для электронных сигарет (или жидкость, используемую в электронных сигарах), в настоящее время являются популярной заменой традиционной сигареты. Известны опубликованные документы, в которых раскрываются композиция жидкости, способ получения жидкости и ее использование. В патенте Китая №200910104922.6 раскрыта предназначенная для выпаривания жидкость для электронных сигарет, которая содержит полиэтиленгликоль 25-90%, пропиленгликоль 9-50% и регулятор вкуса 0,3-52%. Раскрытая жидкость является смешанным продуктом с ароматическими веществами. Предназначенная для выпаривания жидкость для электронных сигарет, раскрытая в патенте Китая №200910310536.2, содержит экстракт табака 3-5% вес/объем, эссенцию табака 3-5% вес/объем, никотин 0-3% вес/объем, стабилизатор 0.2-1% вес/объем, сгущающий агент 3-8% вес/объем, чистую воду 5-10% вес/объем, пропиленгликоль 50-70% вес/объем, кодеина фосфат и хлорфенирамин. Хотя указанная жидкость содержит экстракт табака и имеет вкус традиционной сигареты, она все же представляет собой продукт из экстракта табака и других ароматических веществ. В настоящее время много курильщиков отдают предпочтение электронным сигаретам вместо традиционных сигарет, но недостатки жидкости для этих электронных сигарет являются очевидными. Курильщики заявляют, что вкус электронной сигареты значительно отличается от вкуса традиционной сигареты, хотя электронная сигарета похожа на традиционную сигарету по форме и выпускаемым дымом.Electronic cigarettes using e-liquid (or the liquid used in electronic cigars) are currently a popular replacement for traditional cigarettes. Known published documents, which disclose the composition of the liquid, the method of producing the liquid and its use. China Patent No. 200910104922.6 discloses an electronic cigarette liquid for vaporization that contains 25-90% polyethylene glycol, 9-50% propylene glycol and a taste regulator of 0.3-52%. The disclosed liquid is a mixed product with aromatic substances. The e-liquid intended for vaporization disclosed in China Patent No. 200910310536.2 contains tobacco extract 3-5% w / v, tobacco essence 3-5% w / v, nicotine 0-3% w / v, stabilizer 0.2-1% w / v, thickening agent 3-8% w / v, pure water 5-10% w / v, propylene glycol 50-70% w / v, codeine phosphate and chlorpheniramine. Although this liquid contains tobacco extract and tastes like a traditional cigarette, it is still a product of tobacco extract and other aromatic substances. Currently, many smokers prefer electronic cigarettes instead of traditional cigarettes, but the liquid drawbacks for these electronic cigarettes are obvious. Smokers claim that the taste of an electronic cigarette is significantly different from the taste of a traditional cigarette, although the electronic cigarette is similar to a traditional cigarette in shape and smoke emitted.

Многие курильщики не могут привыкнуть к аромату и вкусу электронной сигареты с жидкостью из ароматических веществ в картридже. Кроме того, ароматические вещества в жидкости для электронной сигареты не могут долго сохранять свои свойства. Срок хранения жидкости для электронных сигарет составляет не более полугода. После долгосрочного хранения жидкость частично или полностью потеряет свои свойства. Эти недостатки значительно снижают качество электронной сигареты и препятствуют распространению электронных сигарет на рынке.Many smokers cannot get used to the aroma and taste of an electronic cigarette with aromatic liquid in a cartridge. In addition, the aromatic substances in e-cigarette liquids cannot retain their properties for long. The shelf life of liquid for electronic cigarettes is no more than six months. After long-term storage, the liquid will partially or completely lose its properties. These shortcomings significantly reduce the quality of electronic cigarettes and prevent the spread of electronic cigarettes in the market.

Сущность настоящего изобретения заключается в создании нового способа получения жидкости для электронных сигарет, устраняющего недостатки жидкости для электронных сигарет в предшествующем уровне техники в отношении аромата, вкуса и срока хранения, а также воздействия на организм человека. Соответственно, технической задачей настоящего изобретения является снижение негативного воздействия на организм человека жидкости для электронных сигарет за счет снижения в ней количества никотина с одновременным сохранением аромата традиционного табака с улучшенным вкусом и увеличением срока хранения такой жидкости.The essence of the present invention is to create a new method for producing liquid for electronic cigarettes, eliminating the disadvantages of liquid for electronic cigarettes in the prior art with respect to aroma, taste and shelf life, as well as effects on the human body. Accordingly, the technical task of the present invention is to reduce the negative effects on the human body of e-cigarette liquid by reducing the amount of nicotine in it while preserving the aroma of traditional tobacco with improved taste and increasing the shelf life of such a liquid.

Для достижения поставленной технической задачи предлагается способ получения жидкости для электронных сигарет, включающий следующие этапы: взвешивают табак в количестве 5-20% вес/объем от объема жидкости для электронных сигарет; помещают табак в бак, добавляют подготовленный растворитель в бак и выдерживают табак в растворителе в течение 30-100 минут; нагревают смесь до 40-60°C и выдерживают в течение 2-8 часов для получения экстракта; фильтруют экстракт для получения фильтрата; добавляют экстракт какао в объеме, эквивалентном 1-10% вес/объем от объема жидкости для электронных сигарет, к фильтрату, перемешивают смесь в течение 20-40 минут, добавляют пропиленгликоль или полиэтиленгликоль до 100% планируемого объема жидкости для электронных сигарет и перемешивают готовую смесь.To achieve the technical task, a method for producing liquid for electronic cigarettes is proposed, which includes the following steps: tobacco is weighed in an amount of 5-20% weight / volume of the liquid volume for electronic cigarettes; place the tobacco in the tank, add the prepared solvent to the tank and keep the tobacco in the solvent for 30-100 minutes; heat the mixture to 40-60 ° C and incubate for 2-8 hours to obtain an extract; filter the extract to obtain a filtrate; add cocoa extract in a volume equivalent to 1-10% weight / volume of the volume of liquid for electronic cigarettes to the filtrate, mix the mixture for 20-40 minutes, add propylene glycol or polyethylene glycol to 100% of the planned volume of liquid for electronic cigarettes and mix the finished mixture .

Предпочтительно использовать растворитель, содержащий пропиленгликоль и/или полиэтиленгликоль в объеме 30-80% (т.е. те же вещества, которые используют на последнем этапе получения жидкости для электронных сигарет) и полисорбат 80 в объеме 0,1-0,5% от объема жидкости для электронных сигарет, которые при подготовке растворителя смешивают и перемешивают в течение 20-40 минут до получения равномерно перемешанного растворителя.It is preferable to use a solvent containing propylene glycol and / or polyethylene glycol in a volume of 30-80% (i.e. the same substances that are used in the last step to obtain liquid for electronic cigarettes) and polysorbate 80 in a volume of 0.1-0.5% of the volume of liquid for electronic cigarettes, which, when preparing the solvent, are mixed and mixed for 20-40 minutes until a uniformly mixed solvent is obtained.

Предпочтительно использовать экстракт какао в виде фильтрата водного экстракта какао, имеющего удельный вес 1,1-1,4, который может быть получен за счет использования следующих этапов: измельчают какао до частиц размером 20-60 меш, помещают порошок какао в бак, добавляют дистиллированную воду в объеме в 3-10 раз больше объема порошка какао, выдерживают в течение 30-90 минут, нагревают смесь до температуры 80-90°C, выдерживают в течение 2-6 часов, выполняют фильтрацию смеси для получения фильтрата и концентрируют фильтрат для получения концентрата фильтрата с удельным весом 1,1-1,4. Водный экстракт не содержит сторонних примесей, которые могли бы негативно взаимодействовать с компонентами жидкости для электронных сигарет.It is preferable to use cocoa extract in the form of a filtrate of an aqueous cocoa extract having a specific gravity of 1.1-1.4, which can be obtained by using the following steps: crushed cocoa to particles with a size of 20-60 mesh, put cocoa powder in a tank, add distilled water in a volume of 3-10 times the volume of cocoa powder, incubated for 30-90 minutes, heated the mixture to a temperature of 80-90 ° C, incubated for 2-6 hours, filtered the mixture to obtain a filtrate and concentrated the filtrate to obtain concentrate fil rata to the proportion of 1.1-1.4. The aqueous extract does not contain third-party impurities that could negatively interact with the components of the liquid for electronic cigarettes.

Предпочтительно, когда используют медицинские и/или пищевые пропиленгликоль и/или полиэтиленгликоль и полисорбат 80.Preferably, when using medical and / or food grade propylene glycol and / or polyethylene glycol and polysorbate 80.

Преимущества и эффективность жидкости для электронных сигарет, полученной таким образом, по сравнению с жидкостью для электронных сигарет, полученной по известным из уровня техники решениям, приведены ниже.The advantages and effectiveness of the e-cigarette liquid thus obtained in comparison with the e-liquid obtained by the prior art solutions are given below.

Использование в настоящем изобретении экстракта какао в заявленном количестве позволяет добиться синергетического эффекта, проявляющегося за счет одновременного достижения следующих технических эффектов:The use of cocoa extract in the claimed amount in the present invention allows to achieve a synergistic effect, manifested due to the simultaneous achievement of the following technical effects:

- обеспечение аромата традиционного табака с улучшенным вкусом жидкости для электронных сигарет за счет сходства действия на организм человека никотина и ряда веществ экстракта какао, таких как теобромин серотонин, а также за счет содержания в экстракте какао какао-масла, удерживающего аромат табака в жидкости;- providing the aroma of traditional tobacco with an improved liquid taste for electronic cigarettes due to the similarity of the effects on the human body of nicotine and a number of substances of cocoa extract, such as theobromine serotonin, as well as due to the content of cocoa butter in the cocoa extract that retains the aroma of tobacco in the liquid;

- увеличение срока хранения жидкости для электронных сигарет за счет содержания в экстракте какао какао-масла, выполняющего функции стабилизатора и антиоксиданта;- increase the shelf life of liquid for electronic cigarettes due to the content in the cocoa extract of cocoa butter, which acts as a stabilizer and antioxidant;

- снижение негативного воздействия на организм человека за счет замещения части никотина в композиции экстрактом какао, ряд веществ которого действует подобно никотину, без ухудшения вкуса традиционного табака, т.е. за счет снижения количества никотина.- reducing the negative impact on the human body by replacing part of the nicotine in the composition with cocoa extract, a number of substances of which act like nicotine, without compromising the taste of traditional tobacco, i.e. by reducing the amount of nicotine.

Кроме того, в настоящем изобретении используется растворитель, содержащий пропиленгликоль или полиэтиленгликоль и полисорбат 80, в качестве экстрагента для прямого получения экстракта табака при нормальных температурных условиях. Благодаря этому, во-первых, жидкость для электронных сигарет приобретает аромат табака; во-вторых, получение экстракта табака при нормальных температурных условиях упрощает технологический процесс и предотвращает потерю и разрушение чувствительного к температуре аромата экстракта табака. Кроме того, по сравнению с другими общепринятыми растворителями, применяемыми для получения экстракта табака, растворитель из пропиленгликоля или полиэтиленгликоля отличается более высокой вязкостью и влажностью и хорошо удерживает аромат табака.In addition, the present invention uses a solvent containing propylene glycol or polyethylene glycol and polysorbate 80 as an extractant for the direct production of tobacco extract under normal temperature conditions. Thanks to this, firstly, the liquid for electronic cigarettes acquires the aroma of tobacco; secondly, obtaining a tobacco extract under normal temperature conditions simplifies the process and prevents the loss and destruction of the temperature-sensitive flavor of the tobacco extract. In addition, in comparison with other conventional solvents used to produce tobacco extract, the solvent from propylene glycol or polyethylene glycol has a higher viscosity and humidity and retains tobacco flavor well.

По оценкам широкого круга курильщиков вкус электронных сигарет, в которых используется жидкость, полученная предлагаемым способом, приближается к вкусу традиционной сигареты даже несмотря на снижение доли никотина за счет замещения ее экстрактом какао. Срок хранения жидкости для электронных сигарет согласно настоящему изобретению составляет 2-3 года. В течение срока хранения аромат жидкости для электронных сигарет остается неизменным.According to estimates of a wide range of smokers, the taste of electronic cigarettes, in which the liquid obtained by the proposed method is used, approaches the taste of a traditional cigarette even despite a decrease in the nicotine content due to its replacement with cocoa extract. The shelf life of liquid for electronic cigarettes according to the present invention is 2-3 years. During the shelf life, the aroma of the liquid for electronic cigarettes remains unchanged.
