摘要： The present invention is a process to make isoprene comprising : a)providing a reaction zone comprising an acidic aqueous solution, b)introducing, continuously or intermittently, in said reaction zone a mixture comprising (i) isobutanol and optionally (ii) t-butanol or an iso-butene precursor which is not isobutanol and not t-butanolor iso-buteneor any combination of two or three of these (ii) components, an aqueous solution of formaldehyde,c)operating said reaction zone at conditions effective to dehydrate isobutanol and optionally (ii) t-butanol and optionally the iso-butene precursor to iso-butene and produce isoprene by reaction of formaldehyde and iso-butene while distilling away a mixture comprising produced isoprene, water, unreacted starting materials and other low boiling point components from this reaction zone to the outside of the reaction zone. In another embodiment isobutanol provides 10% or more of the iso-butenefor the isoprene synthesis. In another embodiment isobutanol provides 20% or more of the iso-butene for the isoprene synthesis. In another embodiment isobutanol provides 30% or more of the iso-butene for the isoprene synthesis. In another embodiment isobutanol provides 40% or more of the iso-butene for the isoprene synthesis. In another embodiment isobutanol provides 50% to 100% of the iso-butene for the isoprene synthesis.
摘要翻译：本发明是一种制备异戊二烯的方法，其包括：a）提供包含酸性水溶液的反应区，b）在所述反应区中连续或间歇地引入混合物，所述混合物包含（i）异丁醇和任选的（ii）或不是异丁醇而不是叔丁醇或异丁烯的异丁烯前体，这些（ii）组分中的两种或三种的任何组合，甲醛水溶液，c）在有效脱水异丁醇的条件下操作所述反应区，任选地（ⅱ）叔丁醇和任选的异丁烯前体与异丁烯反应，并通过甲醛和异丁烯的反应产生异戊二烯，同时蒸馏出包含产生的异戊二烯，水，未反应的起始原料和其它低沸点组分的混合物该反应区到反应区外。在另一个实施方案中，异丁醇提供10％或更多的用于异戊二烯合成的异丁烯。在另一个实施方案中，异丁醇为异戊二烯合成提供20％或更多的异丁烯。在另一个实施方案中，异丁醇为异戊二烯合成提供30％或更多的异丁烯。在另一个实施方案中，异丁醇为异戊二烯合成提供40％或更多的异丁烯。在另一个实施方案中，异丁醇为异戊二烯合成提供50％至100％的异丁烯。
