标 题:Method for synthesis of aliphatic isocyanates from aromatic isocyanates
发明人：LETTMANN CHRISTIAN; KOHLSTRUK STEPHAN; STOCHNIOL GUIDO; SPYROU EMMANOUIL
权利人:DEGUSSA
摘要:The invention relates to a method for synthesis of aliphatic isocyanates from aromatic isocyanates in substantially 3 stages. In particular, the invention relates to a method for synthesis of bis{4-isocyanatocyclohexyl}methane (H 12 MDI) from bis{4-isocyanatophenyl}methane (MDI). More especially, the invention relates to a method for synthesis of H 12 MDI with a trans-trans isomer content of <30%, preferably of <20%, particularly preferably of 5 to 15%.

标题 :Synthesis of polyol bis(allyl carbonate) utilizing reagent recovery and recycle
发明人：YOUNG ELGIN E
权利人:PPG INDUSTRIES INC
摘要:Disclosed is an improved method of forming polyol (allyl carbonate) monomers. In the disclosed method, the organic by-products as diallyl carbonate and unreacted reagents as allyl alcohol are separated from the brine and wash water derived aqueous phase and returned to the allyl carbonate synthesis reaction. The aqueous phase is further separated to recover allyl alcohol therefrom, which is returned to the allyl carbonate synthesis reactor as an azeotrope.

标 题:Process for sulfoalkylation of k-humates
发明人：KLEINHANS GEORGE; STANDER BAREND FREDERIK; HUYSER JOHANNES JACOBUS
权利人:OMNIA GROUP PTY LIMITED
摘要:The invention relates to a process for the preparation of a potassium humate ('K- humate') that is stable at pH of from at least 0.5, optionally including in the presence of divalent and trivalent cations, without aggregation occurring, comprising an initial step of synthesis of a formaldehyde-sodium/potassium bisulphite adduct, prepared via the addition of formaldehyde to a solution of sodium/potassium sulphite, followed by subsequent addition of the formaldehyde-sodium bisulphite adduct to an aqueous solution of K-humate and reacting the mixture at elevated temperatures to obtain the stable K-humate. The invention further relates to methods for stimulating plant growth with the use of the stable K-humate produced by the process of the invention.

标题:Method for synthesis of chalcogenophenes
发明人：HAN CHIEN-CHUNG; KARAPALA VAMSI KRISHNA
权利人:UNIV NAT TSING HUA
摘要:A method of forming a chalcogenophene compound of formula (I) includes reacting a compound of formula (II) with a chalcogenide salt in presence of a proton source. n nY is O, S, Se, Te or Po. R 1 is hydrogen, deuterium, an aliphatic, heteroaromatic, or aromatic group, or a precursor of a leaving group Z whose conjugate acid (HZ) has pK a less than 30. R 2 is hydrogen, deuterium, or an aliphatic, heteroaromatic, or aromatic group. R 1 and R 2 may be the same or different, and may joint together to form a saturated or unsaturated, heteroalicyclic or alicyclic ring. R 3 is, for example, alkyl, aryl, heteroaryl, organosilyl, organotin, or organogermyl. R 3 ′ is the same as R 3 or is hydrogen. X is a precursor of a leaving group X whose conjugate acid (HX) has a pK a of less than 30.
