The composition finds utility as a tooth whitening composition and is applied to the teeth in need of whitening, and then removed when the degree of whitening has been achieved. In certain embodiments, the composition is translucent. Methods for preparing and using the compositions are also disclosed.
专利号:US-2003089435-A1 优先权日:2000-03-23 标题:Method of synthesizing diglycerol tetranitrate, and solid rocket motor propellant containing the same 发明人:SANDERSON ANDREW J; MARTINS LAURA J 摘要:Diglyercol tetranitrate is an energetic nitrate ester plasticizer having no freezing point, making the nitrate ester plasticizer especially suited for use in solid rocket motor propellants that are subjected to low temperature storage and operational environments, which can reach as low as −54° C. in temperature. In order to avoid problems associated with fume-off that characterize the conventional synthesis method of making diglycerol tetranitrate, synthesis is performed in a medium including a mixed acid phase and an inert organic phase. The mixed acid phase contains, as ingredients, at least one nitronium ion source and at least one acid having sufficient strength to generate nitronium ions from the nitronium ion source. The nitronium ions in the mixed acid nitrate diglycerol to form diglycerol tetranitrate, which is then received into the organic liquid. The organic liquid, which preferably is a chlorocarbon such as dichloromethane, is insoluble with diglycerol but soluble with diglycerol tetranitrate. The inert organic phase is then treated to neutralize any acid contained in the inert organic phase, and the diglycerol tetranitrate is separated from the inert organic phase.
专利号:US-10808262-B2 优先权日:2013-12-03 标题:Microorganisms and methods for improving product yields on methanol using acetyl-CoA synthesis 发明人:OSTERHOUT ROBIN E; BURGARD ANTHONY P; PHARKYA PRITI; ANDRAE STEFAN 权利人:GENOMATICA INC 摘要:The invention provides non-naturally occurring microbial organisms containing enzymatic pathways and/or metabolic modifications for enhancing carbon flux through acetyl-CoA. In some embodiments, the microbial organisms having such pathways also include pathways for generating reducing equivalents, formaldehyde fixation and/or formate assimilation. The enhanced carbon flux through acetyl-CoA, in combination with pathways for generating reducing equivalents, formaldehyde fixation and/or formate assimilation can, in some embodiments, be used for production of a bioderived compound. Accordingly, in some embodiments, the microbial organisms of the invention can include a pathway capable of producing a bioderived compound of the invention. The invention still further provides a bioderived compound produced by a microbial organism of the invention, culture medium having the bioderived compound of the invention, compositions having the bioderived compound of the invention, a biobased product comprising the bioderived compound of the invention, and a process for producing a bioderived compound of the invention.
