三甲基一7一氧雙環p ， l ， 0庚烷基什丁烯酮上；醇3種：苯甲醇、 a松油醇、 3 ， 7 ， 11 ， 15十六烯2醇1 ；烷2種：十一烷、十四烷；酚胺2種：姘基甲酚h苯胺、乙酞苯胺；酯、醛、炔、和酸備是1種：丁酸烯丙酯、十八碳醛、十八炔、十六碳酸。The barnidipine hydrochloride were prepared via cyclocondensation from m - nitrobenzaldehyde, methyl acetoacetate and anmmonium bicarbonate, hydrolysis, esterification with opticaliy ( s ) - n - benzyl - 3 - py - rrolidinol, recrystallisation and salification
摘要研究了以碳酸氫銨，間硝基苯甲醛和乙酰乙酸甲酯為原料，經縮合、部分水解，再與（ s ） - n -芐基3 -羥基吡咯烷經酯化、分步重結晶、成鹽得到鹽酸巴尼地平的工藝路線。Thus the term dialkyl carbonate includes, for example, methyl ethyl carbonate
因此術語二烷基碳酸酯包括，例如甲基乙基碳酸酯。Scanning electron microscope ( sem ) and x - ray photoelectron spectroscopy ( xps ) studies indicated that the additive of cs _ 2 took part in the sei film - forming in the process of battery cycles. the elements of carbon, oxygen and fluorin are the main members in the compounds of sei film. sulfur is also one of the main elements of the sei film when the electrolyte included additive of cs _ 2
利用掃描電子顯微鏡和x射線光電子能譜研究表明，二硫化碳在電池的循環過程中參與了sei膜的形成， sei膜的組成物質中主要是c 、 o 、 f三種元素，加入二硫化碳后， s元素也成為主要組分， sei膜的主要組成物質有烷基氧鋰、烷基碳酸酯鋰、碳酸鋰、硫酸鹽、聚烯烴及氟化鋰等。Poly - 3 - hydroxybutyrate ( phb ) and other related polyhydroxyalkanoates ( phas ) are biodegradable thermoplastic polyesters stored in numerous bacteria as carbon and energy reserves and now have been regarded as ideal alternatives to traditional petroleum - derived plastics, which cause severe environmental and waste management problems
聚3 -羥基丁酸酯（ poly - 3 - hydroxybutyrate ， phb ）及其它類型的聚3 -羥基鏈烷酸酯同屬于聚酯類物質，是自然界中多種細菌的碳源及能源儲備物。In this paper, three alkyl substituted dimethyl phosphonates have been synthesized by trimethyl phosphite with 1 - bromopentane, 1 - bromohexane and 1, 2 - dibromoethane. ir, 1h - nmr and 13c - nmr data of these compounds have been reported
摘要以溴戊烷、溴己烷、 1 ， 2 -二溴乙烷和亞磷酸三甲酯為原料，分別合成了戊基、己基、溴乙基取代的三種膦酸二甲酯化合物。並報道了所合成的化合物的紅外光譜、核磁共振氫譜及核磁共振碳譜的數據。The research on the effect of liquid - liquid transition of polyacrylate on crystallization - melting of pdms indicates that above the melting temperature of pdms, pdms is reinforced by a special mutual action between p - electron in carbonyl of polyacrylate and 3d orbit in si atom of pdms, while below the temperature, the pdms crystal is lessened, which can not completely remove the crystal of pdms. however, it is the crystallization behavior of pdms that results in its most segments relaxation being restrained
研究聚丙烯酸酯液一液轉變對聚二甲基硅氧烷結晶一熔融影響的結果表明：碳基碳原子上p電子與出原於中3d軌道相互作用，在聚h甲基硅氧烷熔融轉變溫度以上，對其有分子增強作用；在聚二甲基硅氧烷熔融轉變溫度以下，霎對其有降低結晶度的作用，但不能消除結晶現象。It is to be understood that when in this specification we speak of a dialkyl carbonate and similarly of a dialkyl phenylmalnate, that term does not imply that the two alkyl groups are necessarily the same
有一點要理解：在說明中我們提到二烷基碳酸酯，相似的我們還提到了二烷基苯基丙二酸酯，這兩個術語並不是暗示這兩個烷基官能團必須是一樣的。The polymerization of butyl methacrylate initiated by trichloromethane and tetra - chloromethane were also discussed respectively
同時還分別對以三氯甲烷、四氯化碳為引發劑時甲基丙烯酸丁酯的聚合反應進行了討論。The use of such “ mixed ” dialkyl carbonates may give rise not only to similar “ mixed ” malonates, e. g. the corresponding methyl ethyl phenylmalnate, but also to mixtures of simple malonates
因此使用這種混合二烷基碳酸酯不僅可能得到相似的丙二酸酯，例如相對應的甲基乙基苯基丙二酸酯，而且可能得到簡單丙二酸酯的混合物。分享友人
