摘要:The present invention relates to a process for the synthesis of isocyanates and of isocyanate derivatives. Isocyanates are obtained by reacting an organic halide with a metal cyanate in an organic medium in the presence of a catalyst consisting of a complex of nickel with at least one organic ligand, in which complex the nickel is in the zero oxidation state. A carbamate or a urea, respectively, are obtained by a subsequent reaction with a hydroxy compound or a primary or secondary amine. Isocyanates and their derivatives are used especially either as refined synthesis agents for the production of pesticides and medications, or as monomers or comonomers for the preparation of many macromolecular compounds.

标题:Alkyl tetrahydrofurfuryl ethers as anionic polymerization modifier in the synthesis of rubbery polymer
发明人：HSU WEN-LIANG; HALASA ADEL F; MATRANA BARRY A

摘要:It has been unexpectedly discovered that various compounds, such as alkyl tetrahydrofurfuryl ethers, can be used to modify anionic polymerizations of conjugated diene monomers. These modifiers can be used to polymerize isoprene monomer into high 3,4-polyisoprene at excellent polymerization rates. This is in contrast to the modifiers such as tetramethylethylene diamine which are typically used to modify such polymerizations. This invention more specifically discloses a process for the synthesis of 3,4-polyisoprene which comprises polymerizing isoprene monomer in an organic solvent in the presence of a catalyst system which is comprised of (a) a lithium initiator and (b) a modifier which is an alkyltetrahydrofurfuryl ether selected from the group consisting of ethyltetrahydrofurfuryl ether, propyltetrahydrofurfuryl ether, and butyltetrahydrofurfuryl ether. In the practice of this invention, the utilization of ethyltetrahydrofurfuryl ether is highly preferred since its use results in faster polymerization rates and higher vinyl contents in the resultant polymer.

In the practice of this invention, the utilization of alkyltetrahydrofurfuryl ethers having alkyl groups which contain from 6 to 10 carbon atoms, such as hexyltetrahydrofurfuryl ether, is highly preferred since their use does not results in the creation of odor problems.

标 题:Synthesis of polydiene rubber by high solids solution polymerization
发明人：STACHOWIAK ROBERT W; PUCCIO ANTHONY J; EBERHART THOMAS J

摘要:Synthetic elastomers are typically made commercially by employing emulsion polymerization or solution polymerization techniques. In such solution polymerization techniques, it is desirable to operate at the highest solids content which is practical. As a general rule, it is not practical to prepare such rubbers by solution polymerization at solids contents of higher than about 20 percent. However, the subject invention reveals a technique for preparing such rubbers by high solids solution polymerization at extremely high solids contents. This technique offers substantial advantages associated with eliminating large quantities of organic solvents. The subject invention more specifically relates to a process for the synthesis of polyidene rubber by continuous high solids polymerization which comprises: (1) continuously charging at least one diene monomer, at least one organolithium compound, and from about 4 to about 50 phm of at least one organic solvent into a reaction zone; (2) allowing the monomers to polymerize to a conversion of at least about 90% while utilizing conditions under which there is sufficient evaporative cooling in said reaction zone to maintain a temperature within the range of about 10° C. to about 150° C.; and (3) continuously withdrawing said polydiene rubber from the reaction zone.

权利人:LEE PHIL-HO; KNU INDUSTRY COOPERATION FOUND
摘要:The present invention relates to a novel synthesis method for the formation of carbon-sulfur bonds by the reaction of an organic sulfur-indium complex with nucleophile in the presence of a palladium catalyst. The present invention provides a synthesis method to prepare several kinds of organic sulfides which are difficult to be prepared by the conventional synthesis methods. A short reaction time and quantitative yield are the advantages of this method. In addition, several kinds of organic sulfide can be prepared by the selection of nucleophile and organic sulfur-indium complex to be used.
