摘要:
Disclosed is a process for the treatment of a plant gaseous stream containing odor compounds including hydrogen sulfide, an alkyl mercaptan or an alkyl thiol and mixtures thereof by contacting the plant stream with an oxidizing agent that reduces the odor but forms elemental sulfur. The elemental sulfur, and other inorganic, scales that form, or deposit, can be suppressed or removed using a specific aromatic substituted nonionic surfactant material. The use of such a process produces a significant improvement in odor quality while maintaining a clean process facility and low operating pressure drop.

The invention relates to uncoated and/or coated sodium percarbonate with improved internal stability and storage stability; and, a process that provides uncoated and/or coated sodium percarbonate with improved internal stability and storage stability.
摘要:
The invention relates to particles having a core comprising a peroxy compound with capability of releasing hydrogen peroxide or peroxy acids in aqueous solutions, which particles have a coating containing alkali metal silicate and a chelating agent. The invention also relates to preparation and use of the particles as well as a composition containing such particles.
摘要:
Coated sodium percarbonate particles contain, in the coating, sodium carbonate and also one or more magnesium compounds, preferably magnesium sulfate, optionally in a partially hydrated form, in a single layer or in separate layers in the coating. Preferred coated sodium percarbonate particles contain two layers. Particles are prepared by spraying aqueous solutions containing the coating components onto sodium percarbonate in a fluidized bed with simultaneous evaporation of the water. The particles are suitable for use in detergents, bleaches and cleansing agents.
摘要:
Bleaching compositions are provided that comprise a nitrile containing compound that has the nitrile bonded to a quaternary nitrogen through a methylene unit (where one or both of the normal hydrogens can be substituted), and two of the quaternary nitrogen bonds are part of a saturated ring. This saturated ring contains from two to eight atoms in addition to the quaternary nitrogen. A source of active oxygen will react with the nitrile for bleaching applications. Particularly preferred nitrile containing compounds are N-alkyl morpholinium acetonitrile salts.
摘要:
A particulate bleaching composition is disclosed which comprises particles of an alkali metal salt of percarbonate or mixtures thereof. The particles of the percarbonate bleach are coated and/or agglomerated with a stabilizing effective amount of a hydrophobic ester of citric acid or mixtures of the hydrophobic esters of citric acid.
