It was found that there was some difference in ethanols content, esters content, aldehydes content, and amino acids content between the wine with or without wheat starter addition. 发现用酶制剂替代麦曲发酵时部分醇类、酯类、醛类、氨基酸类物质的含量与加麦曲时存在部分差异。
Not all ethanols are the same. 乙醇与乙醇之间也不尽相同。
Method B was the modified preparation of our laboratory, in which time for washing sperm after fixative, dehydration, and replacing agent were reduced, graded ethanols were increased. 方法:B组减少了固定后洗涤精子、脱水和醋酸异戊脂置换的时间,增加了多级乙醇浓度梯度。
Under optimum conditions, benzylic alcohols, heteroaromatic analogs and substituted α-phenyl ethanols could be oxidized to their corresponding aldehydes and ketones. 在优化条件下,TBN/DDQ/O2体系能够将苄醇类、杂芳香苄醇和取代α-苯乙醇类底物定量地、高选择性地氧化成相应的醛或酮。
In the catalytic cracking researches. concept of effective hydrogen to carbon ratio was introduced, and the co-cracking of compounds in bio-oil with ethanols was done. 在生物油的催化裂化精制过程中,引进了化合物有效氢碳比的概念并考察了生物油内酮类、羧酸化合物与高氢碳比醇类的共裂化性能。
