The present invention relates to a container for holding bulk material, having a closable inlet for the bulk material in the upper closure of the container, a cross-sectional geometry narrowing in the outlet direction for the bulk material, an outlet tube for the bulk material arranged subsequently in the outlet direction, a first reversible mechanical closure device (A), which is arranged in the transition region from the container body to the outlet tube or in the outlet tube itself and, by opening, releases the bulk material from the interior of the container, and a second closure device (B) which reversibly closes the mouth of the outlet tube, the second closure device being a cover which is pressed flush onto the mouth of the outlet tube by means of a closure device, there being a seal which seals the outlet tube in a gas- and liquid-tight fashion from the external environment at least on the contact surface of the cover with the mouth degree of the outlet tube, wherein the cover is screwed onto or is pressed with a clamping ring or a bayonet closure onto the mouth of the outlet tube.

Sealed reusable bulk material container

The present invention relates to a method for reducing or preventing the decomposition of a composition Z comprising Z1 a salt of dithionous acid in an amount ranging from 50 to 100 wt % and optionally Z2 an additive selected from the group consisting of alkali metal carbonate, alkaline earth metal carbonate, alkali metal or alkaline earth metal tripolyphosphate (NaPO), alkali metal or alkaline earth metal sulfite, disulfite or sulfate, dextrose and complexing agents in a combined amount ranging from 0.0001 to 40 wt %, which comprises contacting the components Z1 and optionally Z2 in the solid and/or dry or solvent-dissolved or -suspended state with at least one of the following compounds V in the solid and/or dry or solvent-dissolved or -suspended state, wherein the compounds V are selected from the group consisting of: (a) oxides of the alkali metals lithium, sodium, potassium, rubidium, cesium, or of magnesium, (b) sodium tetrahydroborate (NaBH), (c) anhydrous copper(II) sulfate (Cu(SO)), phosphorus pentoxide and (d) basic amino acids arginine, lysine, histidine, wherein the solvent for Z1, optionally Z2 and V is practically water-free.

Stabilization of sodium dithionite by means of various additives

The present invention relates to a process for the production of bleached wood particles and a process for the production of pale to white wood-base materials which are produced from the bleached wood particles.

Process for the production of bleached wood particles and pale to white wood-base materials

Described is a process for lightening or partially decolorizing vat- or sulfur-dyed textile materials, which comprises treating the material with aminoalkanesulfinic acids in a neutral or weakly acidic medium, and preparations of the aminoalkanesulfinic acids for carrying out this process.
