| titleOfInvention | PROCESS FOR THE MANUFACTURE OF TERT-BUTANOL |
| abstract | Tert isobutanol is made by reacting isobutene with water in the presence of a strongly acid cation exchanger and an anion exchanger. Pref. the ion exchangers are in powdered and/or macroporous granulated form. Suitable cation exchangers are synthetic resin materials contg. SO3- gps., esp. ring sulphonated cross linked styrene-divinylbenzene copolymers. The anion exchangers may be of the pyridine type or those contg. -NR2, =NR or -N gps. where R is H or 1-5C alkyl gp. The presence of the anion exchanger gives higher rates of hydration than when using the cation exchanger alone. In processes employing powdered ion exchangers, the presence of the anion exchanger facilitates removal of the catalyst by filtration. Dehydration of the tert. butanol prod. gives high purity isobutene suitable for the prodn. of isobutene polymers. The wt. ratio anion- to cation exchanger is, e.g. 0.05:1 to 2:1, esp. 0.1:1 to 0.5:1. Hydration of the butene is carried out, e.g. at 20-120 degrees C, esp. 30-100 degrees C, and pref. at pressures of 1.01-30 bar with a wt. ratio water to isobutene of 0.3:1 to 30:1, esp. 1:1 to 15:1. |
