solvent nicotine extraction machine

Product Introduction

Nicotine (also known as nicotine) is an alkaloid present in tobacco, it is widely used in fields such as medicine, pesticides, and electronic cigarettes.
The traditional source of nicotine is extracted from tobacco, but in recent years, with technological advancements, synthetic nicotine (without tobacco sources) has gradually become an important path, especially favored in applications that pursue environmental protection and high purity

The solvent nicotine extraction machine is widely used due to its relatively controllable operation and suitability for laboratory and small-scale production. According to specific process differences, it can be divided into various variants such as direct solvent extraction, alkaline extraction and acid precipitation+extraction, Soxhlet extraction, etc

organic solvent nicotine extraction machine is one of the most common and mature methods for extracting nicotine. Its core is to use alkalization treatment to free nicotine, and then achieve separation and purification through selective extraction with organic solvents. Although this method is highly efficient, it involves flammable and toxic reagents, requiring professional equipment and strict protection。

Extraction process flow (taking typical alkali solvent nicotine extraction method as an example)
1) Raw material pretreatment
Select dry tobacco leaves or cut tobacco, crush and sieve them (such as 45 mesh) to increase the contact area.
2) Alkaline extraction
Add cigarette dust to a 5%~10% sodium hydroxide solution and stir for 15-30 minutes to convert nicotine from a salt state to a free state.
3) Filter and collect the filtrate; Wash the residue with a small amount of water and combine the filtrate.
4) Solvent extraction
Transfer the alkaline filtrate to a separatory funnel, add organic solvents (such as chloroform, ether, carbon tetrachloride, etc.), and shake for 3 extractions.
5) After settling and layering, collect the upper or lower organic phase (depending on the solvent density) and combine the extracts.
6) Concentration and Recycling
Heating distillation is used to remove the solvent and obtain crude nicotine residue.
Attention: Low boiling point solvents such as ether should be avoided from open flames to prevent explosions.
7) Purification and detection
Further purification can be achieved through methods such as recrystallization and column chromatography.
Perform component analysis and purity testing using chromatographic methods such as gas chromatography and high-performance liquid chromatography.
(Additional explanation) In actual industry, "secondary extraction" or "counter current extraction" may also be used to optimize the yield, such as repeatedly extracting and removing impurities after adjusting the pH.

Common extraction solvents: Ethanol can be recovered

solvent nicotine extraction machine is currently one of the main methods for extracting nicotine, with clear principles and strong operational feasibility. It is widely used in scientific research and some industrial production. However, due to its involvement of strong alkali, flammable, explosive, or toxic solvents, and the highly dangerous final product, this process should be carried out in a professional laboratory equipped with fume hoods, protective equipment, and emergency measures.
