有没有对防护内包装或纸板箱的需要? [translate] aReady To Manufacture 准备制造 [translate] aSo high temperature characteristic of MIPI may be one important factor for alkanes’ reactions. 那么高温度典型MIPI也许是一个重要因素为烷’反应。 [translate] ...
Secondly, the test tube was removed and added with a small amount of concentrated sulphuric acid to stop the reaction. Thirdly, the test tube was added with 5 mL of ethyl acetate and then shaken for a few minutes. Finally, the organic solution of the upper layer was removed for ...
Polycyclic aromatics and sulfides are the main materials affecting the catalytic stability, whereas alkanes with different carbon numbers, cycloalkanes, olefins, and monoaromatics have no obvious influence on the durability. The initial hydrogen yields of 0 # diesel of the China National VI standard ...
Aliphatic hydrocarbons occupied the biggest proportion over 86% at 375 A degrees C, mainly in the form of straight-chain alkanes. A few parts of aromatic fragments with small ring numbers will also transfer into intermediate. The heteroatom-containing compounds are mainly alcohols, ketones, amides ...
The results showed that the concentrations of TVOC during straw burning were significantly higher than that in the non-straw burning period in Chengdu. The main components were alkanes, aromatic hydrocarbons and esters in straw burning period while aromatic hydrocarbons, alkanes, esters, aldehydes and...
A detail composition information of fast thermal-cracking products of the OSB was determined by Py-GC/TOF-MS, which mainly contained alkenes (1-alkenes, iso-alkenes and cycloalkenes), alkanes (n-alkanes, iso-alkanes and cycloalkanes), diolefins, aromatics and sulfur-containing compounds. The ...
