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.

Cross-linked sol-gel like materials and cross-linked aerogels, as well as methods for making such cross-linked sol-gel like materials and cross-linked aerogels are described.

The present invention discloses the use of a chlorine-free catalyst in the preparation of diisopropylaminosilane. The chlorine-free catalyst comprises calcium bis(hexamethyldisilazide) and/or strontium bis(hexamethyldisilazide) and diisopropylaminosilane is prepared by a dehydrogenative coupling reaction of monosilane with diisopropylamine catalyzed by a chlorine-free catalyst. The present invention uses a low-cost chlorine-free compound, calcium bis(hexamethyldisilazide) and/or strontium bis(hexamethyldisilazide), as a new catalyst to prepare diisopropylaminosilane, which can effectively catalyze the dehydrogenative coupling reaction of monosilane and diisopropylamine to synthesize diisopropylaminosilane in one step in a yield of 40-65% for diisopropylaminosilane.
