摘要： The invention provides a method of inhibiting the accumulation of DSP scale in the liquor circuit of Bayer process equipment. The method includes adding one or more particular silane based small molecules to the liquor fluid circuit. These scale inhibitors reduce DSP scale formation and thereby increase fluid throughput, increase the amount of time Bayer process equipment can be operational and reduce the need for expensive and dangerous acid washes of Bayer process equipment. As a result, the invention provides a significant reduction in the total cost of operating a Bayer process.

摘要： The invention provides a method of efficiently producing branched, cyclic glycerol-based polyols with a co-product as anti-biodegrading agent from inexpensive readily available glycerol monomer. The method involves polymerizing glycerol or glycerol with at least another monomer to multiple other monomers in the presence of particular amount of a strong base as the catalyst under a particular distillation environment. The polyol produced by the inventive method is beneficial of reducing scales in Bayer liquid for aluminum production process and improving brightness of coated paper substrates without greening effect.
