Definitions
- the invention relates to a process for the preparation of detergents and cleaning agents containing anionic surfactants and detergents and cleaning agents containing anionic surfactants and nonionic surfactants.
- the surfactants are often obtained in their acid form; these free acids are then converted into their washing-active salts in aqueous solution with aqueous neutralizing agents or dry neutralizing agents.
- the aqueous neutralization has the disadvantage that either the mixtures generally have to be dried first in order to be able to use them in solid detergents and cleaners which are obtained by granulation, or the finished granules have to be dried. More recently, it has therefore repeatedly been proposed to convert the surfactants in their acid form into their washing-active form by means of an almost water-free neutralization, through the use of solid alkaline compounds, in particular through sodium carbonate.
- German patent application DE 22 03 552 proposes that during the addition of the acid to an excess of a powdered neutralizing agent and the subsequent granulation in a mixer, a gas is blown through the mixture, which gas contains at least a part of that from the neutralization resulting water transported from the reaction zone.
- European patent application EP 352 1305 proposes a process in which the anionic surfactants in their acid form are neutralized in a mixer with an alkaline solid which is present in excess, the alkaline solid being introduced into the mixer and the anionic surfactant in acid form being slow is added.
- the temperature should not exceed 55 ° C. during the neutralization reaction. In some cases, however, the heat of the neutralization reaction is so strong that normal cooling of the reactor jacket with water is not sufficient, but that the jacket must be cooled with liquid nitrogen in order to prevent agglomeration and lump formation. The task was to develop a simple method which does not have the disadvantages mentioned.
- the invention accordingly relates to a process for the preparation of detergents and cleaning agents containing anionic surfactants by granulation in a mixer, a solid being introduced into the mixer, characterized by
- step (c) Granulation of the constituents to give pourable and free-flowing granules, an organic neutralization medium being used in the case of complete neutralization in step (a), and an inorganic or organic neutra in the case of partial neutralization in step (a) lation medium is used and the solid in step (b) in the case of partial neutralization in step (a) is a basic solid or the solid mixture in step (b) contains one or more basic solids and the basic acting solids or the basic acting solids are present at least in the amounts that a complete neutralization of the anionic surfactants is guaranteed in their acid form.
- the anionic surfactant-containing mixture which comprises the neutralization or the partial neutralization of the anionic surfactants in their acid form, can be prepared in conventional mixers or stirred kettles.
- organic neutralization medium in principle ko ⁇ men all basically acting organic substances, preferably conventional ingredients of solid or liquid detergents and cleaning agents are r considered.
- Liquid organic neutralization media are advantageously used, in particular if a complete neutralization is carried out in step (a).
