摘要： The present invention relates to a container for holding bulk material, comprising a closable inlet for the bulk material in the upper end of the container, a cross-sectional geometry tapering in the outlet direction for the bulk material and an outlet tube for the bulk material which is arranged adjoining in the outlet direction, and a first reversible mechanical closing device (A), which is arranged in the transition region between the container body and the outlet tube or in the outlet tube itself, and which, when opened, releases the bulk material from the container interior, and a second closing device (B) which reversibly closes the opening of the outlet tube, and the second closing device is a cover which is pressed flush on the opening of the outlet tube by a closing device, wherein there is a seal at least on the contact surface of the cover which contacts the rim of the opening of the outlet tube, which seal seals the outlet tube with respect to the external environment in a gas-tight and fluid-tight manner, characterised in that the cover is screwed onto or is pressed onto the opening of the outlet tube with a clamping ring or a bayonet closure.

摘要： The invention relates to a process for the surface treatment of alkali metal dithionite, wherein the alkali metal dithionite is treated with an organic solvent and, in the organic solvent, an alkaline-reacting compound is dissolved to at least 1% by weight, based on the amount of alkali metal dithionite. In addition, the invention relates to surface-treated alkali metal dithionite which has been produced by the aforesaid process for surface treatment.

3 O
10 ), alkali metal or alkaline-earth metal sulfite, disulfite, or sulfate, dextrose, and complexing agent in a total amount in the range of 0.0001 to 40 wt%, wherein the components Z1 and, if applicable, Z2 in a solid and/or dry state or in a state of suspension in a solvent are brought into contact with at least one of the following compounds V in a solid and/or dry state or in a state of suspension in a solvent, wherein the compounds V are selected from the group consisting of: (a) oxides of the alkali metals lithium, sodium, potassium, rubidium, cesium, or magnesium, (b) sodium tetrahydroborate (NaBH
4 ), (c) water-free copper(II) sulfate (Cu(SO
4 )), phosphorus pentoxide, and (d) basic amino acids arginine, lysine, histidine, characterized in that the solvent for Z1, Z2 if applicable, and V is practically free of water.
