Abstract
The invention comprises ethers of formula (a) <FORM:0696125/IV (b)/1> wherein R is an alkyl radicle derived from a primary aliphatic alcohol or a mono- or polyhydroxylated alkyl radicle and ethers of formula (b) <FORM:0696125/IV (b)/2> wherein R is an alkyl radicle, a mono- or polyhydroxylated alkyl radicle, a mono- or dinuclear aryl group or an alkylated derivative thereof. Ethers of formula (a) are made by reacting 1,2-epoxy-2,4,4-trimethyl pentane with a monohydric primary or polyhydric alcohol, e.g. ethylene glycol, propane-1,3-diol, 2-methyl-pentane-2,4-diol and glycerols, in the presence of sulphuric or phosphoric acids or boron trifluoride. Advantageously the alcohol is in large excess. The temperature should not rise substantially above 50 DEG C. except when phosphoric acid is used. Ethers of formula (b) are made by reacting the above epoxide with hydroxy-compounds such as primary fatty alcohols, phenols, cresols, a - or b -naphthol and polyhydric alcohols in the presence of a basic catalyst. Catalysts specified are hydroxides, alkoxides, phenoxides or naphthoxides of alkali metals, e.g. sodium or potassium, and alkali metal salts of lower fatty acids. The temperature is 60-250 DEG C., preferably 100-150 DEG C., with an excess of hydroxy-compound. The ethers may be recovered by extraction with ether or by fractional distillation. In examples the above epoxide is reacted with (1) ethanol, methanol or n-butanol containing sulphuric acid, (2) and (3) methanol containing a boron trifluoride-diethyl ether complex, (4) ethanol and phosphoric acid, (5) ethanol containing sodium, (6) ethanol or isopropanol and sodium ethoxide, (7) ethanol and sodium hydroxide, (8) n-butanol and sodium hydroxide, (9) phenol and ethanol containing sodium hydroxide, (10) lauryl alcohol and sodium hydroxide, (11) b -naphthol and aqueous sodium hydroxide, (12) ethylene glycol and boron trifluoride etherate, (13) ethylene glycol and sodium hydroxide, (14) propane-1,3-diol and boron trifluoride etherate, (15) 2 - methylpentan - 2,4 - diol and boron trifluoride etherate, and (16) glycerol and boron trifluoride etherate to give the required products corresponding to formula (a) or (b). 2(21 - Hydroxyethoxy) - 2,4,4 - trimethylpentan-1-ol formed in (12) is converted to bis-a ,g ,g -trimethyl valerate and a bis-3,5-dinitrobenzoate; 2 - (21,31 - dihydroxy - n-propoxy) - 2,4,4 - trimethylpentan - 1 - ol formed in (16) is converted to a tri-n-nitrobenzoate and 2-(21-hydroxy-n-propoxy)-2,4,4-trimethylpentan-1-ol formed in (14) is converted to the di-n-nitrobenzoate.
