摘要： The present invention provides a method for purifying HFO-1234yf, comprising the steps of (1) cooling a liquid mixture containing HFO-1234yf and HF to separate the mixture into a upper liquid phase having a high concentration of HF and a lower liquid phase having a high concentration of 2,3,3,3-tetrafluoropropene; and (2) subjecting the lower liquid phase obtained in step (1) to a distillation operation to withdraw a mixture containing HFO-1234yf and HF from a top of a distillation column, thereby obtaining substantially HF-free HFO-1234yf from a bottom of the distillation column. According to the present invention, HF and HFO-1234yf contained in a mixture containing HF and HFO-1234yf can be separated under simple and economically advantageous conditions.

摘要： Disclosed is a device (2) for holding a cleaning wiper (1). The holding device includes: a synthetic resin body portion (10) bifurcated to have a pair of support plates (12) to be inserted into a tube (45) of the wiper; and a handle portion (30) extending from the body portion to be held by hand. Each support plate is in an elongated plate form having a width (W1) larger than a thickness (T1). The paired support plates extend parallel with each other to have inner side edges (12b) facing each other and outer side edges (12a) facing in opposite directions. Protrusions (15) having convexly curved edges are integrally formed on the respective outer side edges of the support plates. The paired support plates are elastically deformable to permit tip ends thereof to approach each other.

摘要： Disclosed is a cleaning article to be used while being attached to a holder. The cleaning article includes: a base sheet; a brush portion provided on one side of the base sheet; and a holding sheet provided on the other side of the base sheet. The base sheet, the brush portion and the holding sheet are fusion-bonded together to have at least two fusion-bonded portions which are spaced apart from each other and define a holding space between the base sheet and the holding sheet for accommodating the holder. One of the base sheet, the brush portion and the holding sheet is provided with a color different from those of the others so that the fusion-bonded portions have a color different from that of the holding sheet.
