Preparation of an ethene stream (C 2), a propene stream (C 3), an isobutene and optionally 4C olefin stream (C 4), a 2-methyl-2-butene and optionally 2-butene stream (C 5), and optionally other hydrocarbons containing stream (C x), optionally several separate components containing streams, comprises: (A) a metathesis step, in which a C4-hydrocarbon stream, containing at least 2-butene (15 wt.%), at least isobutene (5 wt.%) and 1-butene (less than 5 wt.%) (feed stream), is contacted with ethene in the presence of usual metathesis catalysts; and (B) separation of the streams (C2, C3, C4 and optionally Cx) from the obtained hydrocarbon stream, with the stream (C5) completely or partially led back to the metathesis step. Independent claims are included for methods for preparing feed stream, comprising subjecting naphtha or other hydrocarbon compounds to steam cracking or fluid catalytic cracking (FCC)-process, or dehydrating butane containing hydrocarbon stream and followed by purifying the obtained C4-olefin-mixture containing isobutene, 2-butene, butadiene, optionally butyne and optionally 1-butene, and removing the obtained stream of C4-olefin-mixture; and removing butadiene and butyne by means of selective hydrogenation to butene or butane hydride, or butadiene and butyne by extractive distillation of the obtained C4-olefin-mixture (raffinate I), where the content of 1,3-butadiene is at a maximum of 1000 wt. ppm.

Abstract: Surprisingly, the drawbacks of previous processes for the preparation of mixtures containing diphenylmethanediisocyanate and polyphenylene-polymethylene-polyisocyanate, e.g. high cost, excessive HCl stripping time, can be avoided by a two-stage reaction of corresponding mixtures containing diphenylmethane-diamine and polyphenylene-polymethylene-polyamine with phosgene in the presence of inert organic solvent. Mixtures containing diphenylmethanediisocyanate and polyphenylene-polymethylene-polyisocyanate (PMDI) having a decreased content of chlorinated side product and decreased iodine colour index are obtained by two-stage reaction of corresponding mixtures containing diphenylmethanediamine and polyphenylene-polymethylene-polyamine (PMDA) with phosgene in the presence of at least one inert organic solvent. The weight ratio of phosgene to HCl in the dwell time apparatus of the second phosgenation stage is (10-30):1 in the liquid phase and (1-10):1 in the gas phase. An Independent claim is included for mixtures containing diphenylmethanediisocyanate and PMDI obtainable by the above process.
