Cracking propan
WebNhận biết. Cracking propan thu được hỗn hợp 3 hiđrocacbon. Dẫn hỗn hợp 3 hiđrocacbon qua dung dịch brom thấy có 24 gam brom phản ứng và thoát ra 4,6 gam hỗn hợp X. Hiệu suất phản ứng cracking là. A. WebSynthesis gas (carbon monoxide and hydrogen) is used to convert bioethanol to propan-1-ol: The reaction is catalysed by a ruthenium-cobalt complex salt. A molybdenum-based catalyst is also being used as it is more resistant to poisoning by sulfur-containing impurities in the feedstock. Subsequently, propan-1-ol is dehydrated to propene:
