  • Publication number: 20230242490
    Abstract: The present disclosure discloses a method for the preparation of sulfinpyrazone, which is produced in two steps with a total yield of 48%, wherein thiophenol as the starting material is electrocatalytically coupled with dichloroethane to obtain 2-chloroethyl phenyl sulfoxide, which then undergoes a substitution reaction with 1,2-diphenyl-3,5-pyrazolidinedione to produce sulfinpyrazone. Compared with the prior art, the present method is characterized by high yield, short steps, less three wastes, good chemical selectivity, no need to use strong bases and oxidants, safe and simple operation, and easy to realize industrial production.

  • Publication number: 20230032707
    Abstract: Systems and methods are provided for controlling one or more optical amplifiers of a C+L band photonic line system (30) of a telecommunications network in which C-band signals and L-band signals may be transmitted. In one implementation, a method (130) may execute a traffic managing module (23). When executed, the traffic managing module (23) may be configured to enable a processing device (12) to calculate (132) a gain correction profile based on a difference between a saved baseline transmission profile (84) and a measured transmission profile (94) of a surviving band of a photonic line system (30) when another band of the photonic line system (30) is missing or impacted. The traffic managing module (23) may further be configured to enable the processing device (12) to apply (134) the gain correction profile to a respective optical amplifier (46) of the photonic line system (30) to compensate for the difference.
