    标题:Method for the Synthesis of Ionizable Lipids Using a Doubly Alkylated Intermediate
    发明人:SAADATI FARIBA; TRAN HUY; CIUFOLINI MARCO; ATMURI N D PRASAD
    权利人:NANOVATION THERAPEUTICS INC
    摘要:Provided herein is a method for the preparation of ionizable, cationic amino lipids using a doubly alkylated nucleophilic intermediate to produce a ketone. The ketone, or a corresponding alcohol, is subjected to one or more synthesis steps to add an ionizable moiety thereto. The method can be advantageously employed for the synthesis of unsymmetrical analogues of the above lipids that would be considerably more difficult to make by alternative strategies. The method can also be used to prepare symmetrical ionizable, cationic amino lipids with fewer steps and/or with the use of fewer hazardous chemicals than known synthesis methods.

    标 题 :Reducing corrosion in reactors used for the synthesis of chromium dioxide
    发明人:OHLINGER MANFRED; WAGNER GERHARD; HONECKER GERHARD; STRITZINGER HEINZ; SPAEHN HEINZ
    权利人:BASF AG
    摘要:In order to reduce corrosion of the inside walls of a reactor made of iron or an iron alloy and used for the synthesis of chromium dioxide by hydrothermal conversion of chromium(VI) oxide with chromium oxides of lower valency, lead or bismuth is added at those points of the reactor at which an aqueous phase occurs during conversion and which do not contact the chromium oxides to be converted. The lead or bismuth may be used in metallic form or in the form of their oxides, hydroxides or salts.
