碳酸二丙酯 的英文怎麼說
中文拼音 [tànsuānèrbǐngzhǐ]
碳酸二丙酯
英文
di-n-propyl carbonate-
Allyl diglycol carbonate resin
碳酸烯丙基二甘醇酯樹脂It is also known that sodium ethylate and diethyl phenylmalonate interact together to give ethyl phenylacetate and diethyl carbonate
眾所周知,乙醇納和二乙基苯基丙二酸酯反應可以得到乙基乙酸苯酯和二乙基碳酸酯。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。Poly ( propylene carbonate ) polyols was synthesized by the copolymerization of carbon dioxide with propylene oxide in the presence of double metallic catalyst in loop reactor
摘要以二氧化碳3環氧丙烷為原材料,在雙金屬氰化物催化劑催化下,利用環流反應器合成聚碳酸亞丙酯多元醇。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 company mainly produces dimethly carbonate, propylene glycol, propylene carbonate, which is the largest per set capacity dmc enterprise
公司主要生產碳酸二甲酯、丙二醇、碳酸丙烯酯。It has further been proposed to make diethyl phenylmalonate by taking the system using an excess of the diethyl carbonate ( which then acts also as solvent ) to force the equilibrium over in the desired direction and distilling out the equilibrium until the reaction has gone substantially to completion
因此我們提出了按照這一系統使用過量的二乙基碳酸酯(後面作為溶劑)強迫平衡向所要的方向移動,當反應基本上完全完成後蒸餾平衡向來生產二乙基苯基丙二酸酯。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
