Uses
Different sources of media describe the Uses of 767-10-2 differently. You can refer to the following data:
1. 1-Butylpyrrolidine can be used in the composition for alcohol recovery solution.
2. 1-Butylpyrrolidine has been used in:microwave-assisted synthesis of ionic liquid precursor, 1-butyl-1-methylpyrrolidinium methylcarbonate.[N,N-methylbutylpyrrolidinium] thiosalicylate, ionic liquid.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 and the reaction parameters optimised to achieve 100% yield of the pyrrolidinium salt with no by-products in under 1h.
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.

The invention provides a method for catalytically synthesizing a 1-substituted pyrrolidine/piperidine derivative by using a supported metal. The method comprises: carrying out a reaction with ammoniato form a pyrrolidine ring/piperidine ring by using a supported metal as a catalyst, using 1,4-butanediol/1, 5-pentanediol as a cyclization raw material and using alcohol as an N-alkylation raw material, wherein the high-selectivity synthesis of the 1-substituted pyrrolidine/piperidine derivative is achieved through the one-step reaction, the active components of the supported metal catalyst are Cu, Ni and Pd/Ru, the total loading capacity of the active components Cu and Ni is 3-15 wt% of the carrier, and the loading capacity of Pd/Ru is 0-1 wt% of the carrier. According to the invention, themethod is simple, low in cost and environmentally friendly, the conversion rate of 1,4-butanediol/1,5-pentanediol is high, the selectivity of the pyrrolidine/piperidine derivatives is high, and the method is a production route with practical application value.
