摘要： An alkylene oxide mixture containing greater than 50% by weight ethylene oxide is continuously polymerized in the presence of a double metal cyanide polymerization catalyst and certain magnesium, Group 3-Group 15 metal or lanthanide series metal compounds. The presence of the magnesium, Group 3-Group 15 metal or lanthanide series metal compound permits the polymerization to be performed continuously without premature deactivation of the double metal cyanide catalyst.

摘要： The invention belongs to energy chemical technical field, especially relates to a fluidized bed reactor and a method for preparation of polyoxymethylene dimethyl ethers from dimethoxymethane and paraformaldehyde. The fluidized bed reactor comprises a gas inlet, a gas distributor, a catalyst inlet, a gas outlet, a fluid inlet, a catalyst outlet, a bottom component and an interstage component, a bottom component related gas upward channel, an interstage component related gas upward channel, a fluid outlet, a bottom downcomer and an interstage downcomer. A process for preparation of polyoxymethylene dimethyl ethers comprises the steps of: fluidizing gas is introduced into a bottom bed from the gas inlet via the bottom component related gas upward channel through the gas distributor; the fluidizing gas goes upwards and flows out of the reactor via the gas outlet; paraformaldehyde and dimethoxymethane are introduced into a bed through the fluid inlet; the fluid goes downwards and leaves the reactor via the fluid outlet. Compared with a conventional cannula reactor, the fluidized bed reactor improves the dispersion uniformity of catalyst and conversion of formaldehyde.

摘要： A convenient process for the manufacture of alkoxylated derivatives of PFPE alcohols is herein provided. The process envisages the use of a boron-based catalyst and an iodine source and is characterized in that a PFPE alkoxide is prepared separately, contacted with a boric acid triester of the same PFPE alcohol and finally submitted to alkoxylation in the presence of an iodine source. The process allows achieving an alkoxylation degree of at least 2 with high yields and under conditions that are convenient on an industrial scale.
