The invention relates to the technical field of chemical synthesis, in particular to a synthetic nicotine salt and a preparation method thereof. A synthetic nicotine salt, the chemical formula is C 10 H 16 N 2 2+ ·(C 7 H 5 O 2 - ) 2 , the synthetic nicotine salt belongs to the orthorhombic crystal system, the P222 space group, and the unit cell parameter is a= 8.1464(3)Å, b=19.2646(5)Å, c=30.8280(4)Å, α=90.00°, β=90.00°, γ=90.00°, V=4651.66(5)Å 3 . The preparation method of the synthetic nicotine salt of the invention is simple and convenient to operate, has good reproducibility, high crystallinity and good stability. The synthetic nicotine salt can reduce the irritation of free nicotine and improve the smoking feeling of the electronic cigarette. |
