36865-43-7 Usage

General Description

1-Chloro-4-ethoxybutane, also known as ethyl 4-chlorobutyl ether, is a chemical compound with the molecular formula C6H13ClO. It is classified as an ether and features a chlorine atom and an ethoxy group attached to a butane backbone. This chemical is commonly used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, and it also has applications in organic synthesis and as a solvent in various industrial processes. 1-Chloro-4-ethoxybutane is a colorless liquid with a characteristic ether-like odor, and it has the potential to be harmful if swallowed, inhaled, or absorbed through the skin. It is important to handle this chemical with care and adhere to safety precautions when working with it.

Check Digit Verification of cas no

The CAS Registry Mumber 36865-43-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,8,6 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 36865-43:
(7*3)+(6*6)+(5*8)+(4*6)+(3*5)+(2*4)+(1*3)=147
147 % 10 = 7
So 36865-43-7 is a valid CAS Registry Number.

ON THE MECHANISM OF SELECTIVE CHLORINATION OF ETHERS WITH SULFURYL CHLORIDE IN THE DARK

Buyck, Laurent De,Pooter, Herman De

, p. 807 - 816 (2007/10/02)

Alkyl 4-chlorobutyl ethers reacted in the dark with an excess of sulfuryl chloride at 70-85 deg C (bath) to afford α,β,β-trichlorinated ethers.The reactions were accelerated 3- to 6-fold by N,N-dimethyloctylammonium salts (0,12 to 1 mmol/mol ether).This catalyst promoted decomposition of sulfuryl chloride to chlorine and sulfur dioxide and thereby caused serious loss of sulfuryl chloride.The proportions of chlorination at α or α1 position were identical in the catalyzed or uncatalyzed version and depended on inductive effects, correlating well with Taft's linear free energy relationship log k/kref=ρ*?* for R = H, Me, Et, Pr in RCH2O(CH2)4Cl with ρ* = -2.6 +/- 0.1.The overall reactivity of ethers appears to vary like the nucleophilicity of the ether oxygen.It is concluded that hydride abstraction occurs indirectly, probably involving a chloroxonium ion pair.
