PRODUCTION METHOD OF ETHER BOND-CONTAINING COMPOUND
-
Paragraph 0038, (2018/02/08)
PROBLEM TO BE SOLVED: To provide a method for producing a colorless ether bond-containing compound by suppressing problems of foaming of a reaction liquid, vibration of a reactor or contamination even when in the case of industrial production scale of an ether bond-containing compound. SOLUTION: A method of producing an ether bond-containing compound having a specific structure includes: a step of making an epoxy group-containing compound having a specific structure and alcohol having a specific structure react; a first purification step of removing the alcohol having a specific structure contained in a reaction solution after the reaction step; and a second purification step for removing alcohol having the specific structure from the reaction solution after the first purification step by distilling while introducing an inert gas, in which a flow rate of the inert gas introduced in the second purification step is from 2.0 to 4.5 mole per hour relative to charging molar number of the reaction step of the epoxy group-containing compound having a specific structure.

Silica sulfuric acid; an efficient and reusable catalyst for regioselective ring opening of epoxides by alcohols and water
Salehi, Peyman,Dabiri, Minoo,Zolfigol, Mohammad Ali,Fard, Mohammad Ali Bodaghi
, p. 1113 - 1121 (2007/10/03)
The nucleophilic ring opening reactions of epoxides by aliphatic alcohols and water are achieved efficiently in the presence of catalytic amounts of silica sulfuric acid with high degree of regioselectivity. The catalyst is reusable and can be applied several times without any decrease in the yield of reactions.

Yatluk,Suvorov,Khrustaleva,Chernyak
, p. 769 - 772 (2007/10/03)
Nucleophilic opening of the oxirane ring in 2,3-epoxypropyl ethers with alcohols in the presence of titanium alkoxides and other catalysts was studied. The mechanism of catalysis by titanium alkoxides was discussed on the basis of comparison with acid-bas
Magnesium hydrogensulfate: A cheap and efficient catalyst for the conversion of epoxides into β-alkoxy alcohols, vicinal-diols, and thiiranes
Salehi, Peyman,Khodaei, Mohammad Mahdi,Zolfigol, Mohammad Ali,Keyvan, Afsaneh
, p. 3041 - 3048 (2007/10/03)
The nucleophilic ring opening reactions of epoxides by aliphatic alcohols and water are achieved efficiently in the presence of catalytic amounts of magnesium hydrogensulfate, Mg(HSO4)2, with high degree of regioselectivity. The reactions are chemoselective and many of the other functional groups such as ethereal carbon oxygen bonds as well as carbon-carbon double bond remain intact under the reaction conditions. Epoxides also react with thiourea or ammonium thiocyanate in the presence of Mg(HSO 4)2 to afford the corresponding thiiranes in good to excellent yields.
