Latest Patents

Among Edwin D Little's latest patents are two significant inventions. The first patent addresses a method of preparing reproducibly stable aqueous suspensions of sodium. This invention focuses on creating aqueous sodium dithionite slurries or suspensions that remain nonsettling during transport and can be pumped after being stored at temperatures between 32°F and 40°F for at least fourteen days. The composition comprises roughly 34% sodium dithionite, 0.17% xanthan gum, 5.5-6.5% 50% sodium hydroxide, 0.26% chelate, and 1.96% sodium tripolyphosphate added after the sodium dithionite.

His second notable patent discusses stabilized dithionite solutions. In this innovation, guar and xanthan gums are utilized as additives to enhance the stability of sodium dithionite aqueous solutions when exposed to air. This development is particularly useful in vat dyeing of textiles and bleaching processes, with these gums being added at levels between 0.1% to 0.2%, ideally at 0.15% by weight. This unique combination has improved the stability of these solutions by more than 100-200%.
