摘要:
The present invention relates to a method of removing bisfluoromethyl ether contained in fluoromethyl-1,1,1,3,3,3-hexafluoroisopropyl ether in a simple, effective manner, and is characterized in that fluoromethyl-1,1,1,3,3,3-hexafluoroisopropyl ether containing bisfluoromethyl ether is brought into contact with zeolite.
摘要:
A forceps, comprising: a pair of forceps members, being able to open or close at one end, so as to put an object between them, and being supported at the other end thereof; a driving wire for transferring tension thereon to the forceps members for bringing them to open and close; and a driver portion for giving the tension onto the driving wire, wherein: one of the forceps members is built up with a member (A) 41, being able to open or close at one end, so as to put the object between them, while being supported to freely rotate at the other end, and the other member with a member (B) 42, being able to put the object between them, but being supported fixedly at the other end; the driving wire 44 is wound around a rotary portion at the other end of the member (A) 41, and a portion of the wound portion thereof is fixed onto the rotary portion; and a tension for open and close operation is given from the driver portion to one end of the driving wire 44. Also, this forceps is inserted into inside of a manipulator, to be used therewith.

The present deodorizing substance is obtained by treating a raw material selected from sugar cane juice and sugar cane-derived molasses by column chromatography, and characterized in that the substance is a fraction obtained by passing the aforesaid raw material through a column packed with a synthetic adsorbent as a fixed carrier and eluting ingredients adsorbed on said synthetic adsorbent with a solvent selected from water, methanol, ethanol and a mixture thereof. The present deodorizing substance is inexpensive and has high safety. It may be used widely in foods and environmental protection fields.
摘要:
It is possible to obtain fluoromethyl-1,1,1,3,3,3-hexafluoroisopropyl ether which has a high purity and in which an impurity making the purification by distillation difficult has been removed, by contacting a crude fluoromethyl-1,1,1,3,3,3-hexafluoroisopropyl ether with a Bronsted acid(s), a Lewis acid(s) or an acid(s) fixed to a resin or the like.

A hardly gas permeable and airtightly sealed package encloses a container containing infusion. The package also encloses an amount of deoxidizing agent. The package comprises a hardly deformable tray and a flexible lid bonded to the flange of said tray. The container comprises a discharge port, a container main body and a neck connecting said port and said main body. A jagged or irregular portion having a profile corresponding to that of the port and neck is integrally formed with the tray. The irregular portion controls the movement of the container relative to the package.
