    摘要: A polyglycerol composition contains diglycerol, triglycerol, and tetraglycerol each in a content of 5 percent by weight or more, has a total content of diglycerol, triglycerol, and tetraglycerol of 75 percent by weight or more, has a total content of higher polyglycerol components of 10 percent by weight or less, the higher polyglycerol components each having a degree of polymerization of 7 or higher, and is substantially free from chlorine atom. A process prepares a polyglycerol composition by reacting glycerol and/or a polyglycerol with glycidol in the presence of an activated carbon catalyst.

    摘要: An ejector capable of generating a high negative pressure capable of sucking and conveying fine metal pieces such as cuttings, for example, in a case of using the ejector as a driving source for a fluid conveyor, comprising a convergent-divergent nozzle having a throat formed between a suction port and a discharge port in which jet blowing holes are formed in the convergent-divergent nozzle for jetting a jet stream from the upstream to the downstream of the throat thereby forming a negative pressure, wherein pressure control holes are formed being opened to the downstream of the jet blowing holes for communicating a pressure space at a level higher than a negative pressure formed by the jet stream and lower than a static pressure of the jet stream and the inside of the convergent-divergent nozzle.
