Description
1-Butylpyrrolidine is an organic compound with the chemical formula C8H17NO. It is a colorless liquid with a characteristic amine-like odor. It is soluble in water and organic solvents, and is commonly used as a building block for the synthesis of various ionic liquids and other chemical compounds.
Uses
1-Butylpyrrolidine is used as a component in the composition for alcohol recovery solution. It helps in the separation and purification of alcohol from other components in the solution.
Used in Chemical Synthesis Industry:
1-Butylpyrrolidine is used as a precursor for the synthesis of ionic liquids. It has been used in the microwave-assisted synthesis of ionic liquid precursors such as 1-butyl-1-methylpyrrolidinium methylcarbonate, [N,N-methylbutylpyrrolidinium] thiosalicylate, and other ionic liquids.
The reaction of 1-butylpyrrolidine with dimethyl carbonate to yield the ionic liquid precursor, 1-butyl-1-methylpyrrolidinium methylcarbonate, has been investigated under microwave heating conditions. The reaction parameters have been optimized to achieve a 100% yield of the pyrrolidinium salt with no by-products in under 1 hour. This makes 1-butylpyrrolidine a valuable intermediate in the synthesis of ionic liquids, which have a wide range of applications in various industries, including pharmaceuticals, materials science, and energy storage.
Preparation
The synthesis of 1-butylpyrrolidine and its derivatives (1-butylpyrrolidine with a little of 1-butenylpyrrolidines) was developed via a one-pot method from ammonia and 1,4-butandiol. Here, the product of 1-butylpyrrolidine was emphatically investigated, and the yield was 76% under the optimized conditions. Such a route was realized through successive N-alkylation using aqueous ammonia as the nitrogen source over the CuNiPd/ZSM-5 catalyst, which was prepared by a simple incipient wetness method. In this route, 1,4-butandiol not only participated in the formation of the N-heterocycle, but also acted as an alkylating reagent. This work offers a straightforward, economical route for 1-butylpyrrolidine and its derivatives.One-pot synthesis of 1-butylpyrrolidine and its derivatives from aqueous ammonia and 1,4-butandiol over CuNiPd/ZSM-5 catalysts
Check Digit Verification of cas no
The CAS Registry Mumber 767-10-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 7 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 767-10:
(5*7)+(4*6)+(3*7)+(2*1)+(1*0)=82
82 % 10 = 2
So 767-10-2 is a valid CAS Registry Number.
