摘要:The present invention is the method for incorporation of acetal and acetal ester groups for protection of hydroxyl function. The method is applied in particular in the processes of RNA synthesis. The method can be employed in the synthesis of nucleosides with acetal and acetal ester groups for the protection of hydroxyl functions. The method according to the invention consists of the reaction of an organic compound containing at least one hydroxyl group, soluble in an aprotic solvent, with a compound of the general formula 1, R 1 -S-CH 2 -O-R 2 (1) in the presence of SnCl 4 , in an aprotic solvent. In the second aspect, the present invention is the method of protecting the hydroxyl function, particularly in position 2', in nucleoside derivatives, based on the incorporation of an acetal or acetal ester group.

摘要:The present invention discloses a fiber-grade polyphenylene sulfide resin synthesis method, taking sodium bisulfide and p-dichlorobenzene as raw materials, N-methyl pyrrolidone as the solvent and C5-C6 fatty acid salt formed through dehydration to C5-C6 fatty acid and sodium hydroxide as the polymerization additive for synthesis through polymerization. White polyphenylene sulfide resin is obtained through acidification and washing of reaction slurry. In view of the fact that MFR is below 125 g/10 min, weight-average molecular weight as measured by GPC is over 4.2×10 4 , and whiteness is over 90, it can satisfy requirements for fiber polyphenylene sulfide resin. C5-C6 fatty acid salt according to the method of the present invention has a higher solubility in NMP, which can better promote polymerization. It is to be fully diverted into the filtrate after filter prior to conversion into free fatty acid again through acidification with hydrochloric acid. C5-C6 fatty acid is available for azeotropy with water, which has a limited solubility in water. Therefore, it is applicable to recycle C5-C6 fatty acid from the filtrate through azeotropy with water, and thereby solve the problem with separation of additive and sodium chloride that are soluble in water.
