Patent DK-84781-A (DK)
Inventor: ROMANO U
IPC: C07C68/06
Filed: 1981-02-25
Abstract: The application relates to a process for synthesising carbonic allyl esters from polyhydric alcohols, which are reacted with diallyl carbonate in the presence of a basic catalyst, which can be chosen from sodium hydroxide, sodium carbonate, sodium alcoholate, organic bases or basic ion exchange resins.The final products obtained differ according to the ratio of the components of the starting mixture. Thus, in the case of diols with a diallyl carbonate/diol ratio greater than or equal to 10, the resultant product is constituted by the bis allyl carbonate of the diol together with a quantity of less than or equal to 10% of oligomers represented mainly by dimers. If the ratio is less than 10, the percentage of oligomers rises until, in the case of an approximately stoichiometric ratro, it reaches a value close to 70% of the reaction product.

Abstract: 640,065. Purifying gas. THORNE, W. F., and BOURNEMOUTH GAS & WATER CO. Jan. 8, 1948, No. 599. Drawings to Specification. [Class 55(ii)] In the removal of hydrogen sulphide from gas, the gas is passed substantially vertically through a chamber containing the purifying material, which includes iron oxide, agglomeration of the material being avoided by regulating the water content of the material entering the chamber, and by regulating the rate of discharge of the material from the bottom of the chamber. Normally, water is added to the entering material, e.g., by sprinkling. The partially fouled material is returned, after revivification with air if necessary, to the top of the chamber, or revivification may be effected in the chamber by providing the necessary oxygen content to the gas to be purified, in which case the material is returned directly to the top of the chamber. The process may be effected in more than one chamber, the material being transferred, with or without revivification, from the base of one chamber to the top of another, and the gas passing in counterflow through the chambers in sequence. The free sulphur may be removed, partly or completely, from the revivified material before it is returned to the top of the chamber. The purifying process may be operated at atmosphere pressure, or at higher or lower pressures, and the chamber may be jacketed for temperature regulation. Specifications 266,586 and 321,536.
