Abstract: The described technology is generally directed towards automatic storage of data/digital objects in a self-adaptive replication system. Data replication can be switched between synchronous (sync) replication and asynchronous (async) replication between a local storage system and a remote storage system. Latency between writing data to the local storage system and the remote storage system can be determined. In the event of the latency is less than a threshold value, sync replication can be utilized, and in the event of the latent is greater than the threshold value, async replication can be utilized. Accordingly, data replication can adapt based on infrastructure, volume of data to be write, period(s) of no-data writes, etc. Async replication can use a buffer to temporarily store data during a write operation at the remote storage system. Alternatively, a list can be maintained for data to write to the remote storage system for subsequent replication.

Abstract: In a method for acetylene hydrochlorination to vinyl chloride catalyzed by ultra-low content aurum-based material, a nitrogen-modified activated carbon support is obtained by using 1,10-phenanthroline as a modifier. A trace amount of aurum is used as a main active component and an organic solvent with a low polarity and a low boiling point, isopropanol, is used as a solvent.
