摘要:氢氧化钠可大大促进有机硼烷与碘的反应.衍生自末端烯烃的有机硼烷利用与硼相连的三个烷基中的大约两个进行反应,从而提供最高67%的烷基碘产率.因此,1-癸烯的硼氢化碘化得到正癸基碘化物的60%收率.衍生自内部烯烃的仲烷基反应较慢,并且与硼连接的三个烷基中只有一个被转化为碘化物.因此,应用于2-丁烯的方法提供了30%产率的2-丁基碘化物.使用二亚氨基硼烷双-(3-甲基-2-丁基硼烷,Sia 2Bh)作为硼氢化剂可提高末端烯烃的碘化物收率,因为伯烷基优先于仲唾液酸基反应.因此,将1-癸烯与sia 2 Bh进行氢硼化,然后进行碘化,得到95%的正癸基碘化物.用甲醇的甲醇钠代替氢氧化钠可提供相当高的收率的烷基碘.在碱的存在下,硼氢化与碘化的结合为烯烃的抗-Markovnikov加氢碘化提供了一种方便的方法.与配置在反应中心的倒置有机硼烷进行的碱诱导的碘化,如通过形成内从三-2Iodonorbomane外-降冰片基硼烷.

标题 :Preparation of alkylidene diesters
发明人：PAULIK FRANK E; SCHULTZ ROBERT G
权利人:MONSANTO CO
摘要:Alkylidene diesters such as ethylidene diacetate are produced by reacting an ether and/or an ester under substantially anhydrous conditions with carbon monoxide and hydrogen in contact with a catalyst system comprising a rhodium compound and a halogen component at a temperature in the range from 125° to 300° C. and at a carbon monoxide partial pressure in the range from about 1.0 to 1100 kg/cm 2 . When ethylidene diacetate is the product, it can then be decomposed to produce vinyl acetate and acetic acid by well-known techniques. Since one mole of acetic acid is also produced in the synthesis of the diacetate, the invention makes possible an overall process for the production of vinyl acetate which produces acetic acid rather than consumes it.

摘要:Alkylidene diesters such as ethylidene diacetate are selectively produced in high yields by reacting an ether and/or an ester under substantially anhydrous conditions with carbon monoxide and hydrogen in contact with a catalyst system comprising a rhodium compound, a halogen component, a palladium cocatalyst and a promoter component which is an agent for liberation of carboxylic acid anions. The process is carried out in the liquid phase in a solvent comprising a carboxylic acid at a temperature in the range of 150 DEG to 190 DEG C. and at a carbon monoxide partial pressure in the range from about 1.0 to 1100 kg/cm2 and a carbon monoxide/hydrogen mole ratio of 6:1 to 1:2 for the ester reaction and 10:1 to 1:2 for the ether reaction. When ethylidene diacetate is the product, it can then be decomposed to produce vinyl acetate and acetic acid by well-known techniques. Since one mole of acetic acid is also produced in the synthesis of the diacetate, the invention makes possible an overall process for the production of vinyl acetate which produces acetic acid rather than consumes it.

摘要:The present invention provides various processes for producing methanol and ethanol, preferably in a mixed alcohol stream. In one embodiment, the invention includes directing syngas to a synthesis zone wherein the syngas contacts a methanol synthesis catalyst and an ethanol synthesis catalyst (either a homologation catalyst or a fuel alcohol synthesis catalyst) under conditions effective to form methanol and ethanol. The methanol and ethanol, in a desired ratio, are directed to an oxygenate to olefin reaction system for conversion thereof to ethylene and propylene in a desired ratio. The invention also relates to processes for varying the weight ratio of ethylene to propylene formed in an oxygenate to olefin reaction system.
