10种脂肪酰乙醇胺制备工艺优化及其结构表征Process optimization of preparation of 10 fatty acid ethanolamines and its structural characterization

Zhongguo youzhi, 2022
为了优化脂肪酰乙醇胺的制备工艺，以油酸甲酯和乙醇胺为原料，采用无溶剂法制备油酰乙醇胺，采用单因素实验优化了反应条件。然后以10种脂肪酸甲酯为原料，考察了该反应方法的普适性，并对制备得到的10种脂肪酰乙醇胺的结构进行了表征。结果表明：制备油酰乙醇胺的最佳工艺条件为无溶剂、油酸甲酯与乙醇胺物质的量比1∶ 5、反应温度100 ℃、反应时间15 h，在此条件下油酰乙醇胺产率为76.52%；在最佳工艺条件下考察了反应底物的普适性，得到10种脂肪酰乙醇胺目标化合物，其产率在53%~87%之间，并通过核磁氢谱 ...

Characterization of occupational exposures to cleaning products used for common cleaning tasks-a pilot study of hospital cleaners [PDF]

, 2009
Background In recent years, cleaning has been identified as an occupational risk because of an increased incidence of reported respiratory effects, such as asthma and asthma-like symptoms among cleaning workers. Due to the lack of systematic occupational

Dietary food patterns as determinants of the gut microbiome–endocannabinoidome axis in humans

Scientific Reports, 2023
The gut microbiota and the endocannabinoidome (eCBome) play important roles in regulating energy homeostasis, and both are closely linked to dietary habits. However, the complex and compositional nature of these variables has limited our understanding of

Integrating transcriptome and metabolome to identify key genes regulating important muscular flavour precursors in sheep

Animal, 2022
Flavour precursors are the basis of meat flavour, and their metabolism is regulated by a variety of enzymes. Thus, it is of great significance to identify the key genes related to meat flavour precursors.
