WARNING: This product contains nicotine. Nicotine is an addictive chemical.
The following contains information regarding the nicotine extraction process utilized by the nicotine suppliers of MyFreedomSmokes.com. For more information regarding this process please contact DustinT@MyFreedomSmokes.com
When it comes to nicotine extraction the distillation process is the preferred method of removing the natural impurities from the plant based liquid. Most pharmaceutical grade manufacturers prefer this method and this is the method used to extract the nicotine sold at MyFreedomSmokes.
An alternative practice is to utilize salt processing to turn the liquid into a sulfate. This process requires a bleaching agent to remove the impurities and then it is reconstituted with a liquid to turn it back into a useable form. Due to the bleaching agent introduced in this process, the nicotine sulfate product is often mistaken as being more pure. This is a common misconception because the bleached liquid appears more clear in appearance in comparison to the slightly tinted freebase derived from the more refined and preferred distillation process.
Freebase nicotine is also a very reactive chemical and it will often change color in solution. In freebase form it tends to be clear with a slight yellow or brown hue. Once mixed, the range of colors it turns depends on what it's mixed with, though pink is typical in PG, and yellow in VG.
Regardless, the color of the nicotine is a purely cosmetic factor. Nicotine will always have varying shades of color since it reacts over time. The main agents of reaction are light, heat, and exposure to free oxygen, but different flavoring compounds can also contribute to color changes.
For best storage conditions, keep it cold, keep it dark, and keep it airtight as this will best mitigate any changes from occurring. However, don't worry if it darkens as the consistency will be the same and the flavor isn't unduly affected. Even aged e-liquid that has been exposed to ambient light and in a bottle half-full of air should still deliver the same quality nicotine.
Nicotine alkaloid (plural nicotine alkaloids)
Most organic alkaloids are well-defined crystalline substances which unite with acids to form salts. In the plant they may exist in the free state, as Salts or as N-oxides. In addition to the elements carbon, hydrogen and nitrogen, most alkaloids contain oxygen. A few, such as nicotine from tobacco, are oxygen-free and are liquids
Knowledge of the solubility of alkaloids and their salts is of considerable pharmaceutical importance. Not only are alkaloidal substances often administered in solution, but also the differences in solubility between alkaloids and their salts provide methods for the isolation of alkaloids from the plant and their separation from the non-alkaloidal substances that are also present. While the solubility’s of different Alkaloids and salts show considerable variation, as might be expected from their extremely varied structure, it is true to say that the free bases are frequently scarcely soluble in water but highly soluble in organic solvents; with salts the reverse is often the case, these being usually soluble in water but scarcely soluble in organic solvents.
EXTRACTION OF NICOTINE ALKALOIDS
Extraction methods vary with the scale and purpose of the operation, and with the raw material. For many research purposes chromatography gives both speedy and accurate results. However, if an appreciable quantity of alkaloid is required, one of the following general methods will usually serve.
The material is moistened with water and mixed with lime which combines with acids, tannins and other phenolic substances and sets free the alkaloids (if they exist in the plant as salts). Extraction is then carried out with organic solvents such as ether or petroleum spirit. The concentrated organic liquid is then shaken with aqueous acid and allowed to separate. Alkaloid salts are now in the aqueous liquid, Volatile liquid alkaloids such as nicotine and coniine are most conveniently isolated by distillation. An aqueous extract is made alkaline with caustic soda or sodium carbonate and the alkaloid distilled off in steam. Leaving most of the impurities behind in the remaining organic liquid.
The material is extracted with water or aqueous alcohol containing dilute acid. Pigments and other unwanted materials are removed by shaking with chloroform or other organic solvents. The free alkaloids are then precipitated by the addition of excess sodium bicarbonate or ammonia and separated by filtration or by extraction with organic solvents.
Large-scale extractions based on the above principles are sometimes done in the field and the crude mixtures of alkaloids afterwards sent to a factory for separation and purification.
The separation and final purification of a mixture of alkaloids may sometimes be done by fractional precipitation or by fractional crystallization of salts such as oxalates, tartrates or picrates (salts). Chromatographic methods are particularly suitable if the mixture is a complex one and if small quantities of alkaloids will suffice.
