Preparation of propene

A multistage process for preparing propene, in which the first stage is the reaction of 1-butene, 2-butene and isobutene to give propene, 2-pentene and 2-methyl-2-butene in the presence of a metathesis catalyst comprising at least one compound of a metal of transition group VIb, VIIb or VIII of the Periodic Table of the Elements; the second stage is separation of the propene and 2-pentene/2-methyl-2-butene formed; the third stage is reaction of the 2-pentene and 2-methyl-2-butene with ethehe to give propene, 1-butene and isobutene in the presence of a metathesis catalyst comprising at least one compound of a metal of transition group VIb, VIIb or VIII of the Periodic Table of the Elements; the fourth stage is separation of the propene and 1-butene/isobutene formed and returning the 1-butene and isobutene formed to the first stage.

The effect of material purity on the optical and scintillation properties of solution-grown trans-stilbene crystals

Large, 10 cm-size, single crystals of trans-stilbene were grown for the first time from solution by a temperature reduction technique. Their scintillation performance for fast neutron detection depended on the purity of the initial starting material. A light-yield-inhibitor-free starting material was specially synthesized and crystals from this material were compared to those grown from commercially available powders of trans-stilbene. The use of pure material made possible the growth of the large size crystals (>400 g) with excellent neutron-gamma discrimination performance, which are needed for use as a radiation detection material.

Cycloisomerization promoted by the combination of a ruthenium-carbene catalyst and trimethylsilyl vinyl ether, and its application in the synthesis of heterocyclic compounds: 3-Methylene-2,3-dihydroindoles and 3-methylene-2,3- dihydrobenzofurans

Substituted N and O heterocycles have been synthesized by the cycloisomerization of dienes using a ruthenium-carbene catalyst. The products obtained with and without trimethylsilyl vinyl ether differ (see scheme, Cy = cyclohexyl, Mes = 2,4,6-trimethylphenyl, Ts = p-toluenesulfonyl).

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 172222-30-9 is helpful to your research., Related Products of 172222-30-9

Sequential olefin metathesis – Intramolecular asymmetric Heck reactions in the synthesis of polycycles

Application of the intramolecular asymmetric Heck reaction in the desymmetrization of a novel class of symmetrical bicyclodienes, synthesized through a diastereoselective double ring-closing metathesis (DSRCM) reaction, was achieved with good yields (approximately 80%) and excellent enantioselectivities (up to 99% ee). Three contiguous stereocenters are established in a single desymmetrization reaction. The use of thallium carbonate as base in the asymmetric Heck reaction favours double bond migration in 13. Cationic conditions delivered products with good to excellent enantioselectivities, surpassing the results under neutral conditions.

PROCESS FOR CO-PRODUCING OLEFINS AND DIESTERS OR DIACIDS STARTING FROM UNSATURATED FATS

In order to produce both an olefinic fraction and a composition of diacids or diesters of fats, a process is carried out which comprises, in succession: a) metathesis of an unsaturated fat with ethylene in the presence of at least one non-aqueous ionic liquid; b) separating and recycling the ionic liquid used in the first step; c) separating, by distillation, the olefinic fraction (fraction A) from the unsaturated fat mono-ester or mono-basic acid fraction (fraction B) formed in step a); d) homometathesis of the mono-unsaturated fat ester or acid cut (fraction B) which allows the co-production of unsaturated fat diesters or diacids (fraction C) and ethylene which is recycled to the first methathesis step of the process; and e) optionally, recycling the ionic liquid containing the catalyst used in step d). Of particular application to an oleic sunflower oil, an oleic rapeseed oil or to a mixture of mono-alcohol esters of said oils, whereupon the process can produce both an olefinic fraction (mainly composed of 1-decene) and a composition of diesters or diacids wherein, in general, over half of the chains is constituted by unsaturated C18 chains (mainly composed of octadecene-9 1,18-diacid or diester) and to recycle the ethylene employed.
