Definitions
- the present invention relates to a process for the manufacture of detergents containing sodium tripolyphosphate, by spray-drying a spray slurry including the detergent components.
- Sodium tripolyphosphate is known to increase the viscosity of detergent slurries. This is the result of the hydration sodium tripolyphosphate undergoes to form the hexahydrate. 1n the production of detergents, attempts are being made with the object of transforming quantitatively the sodium tripolyphosphate into hexahydrate, so as to enable the slurry, which is sprayed while hot, to produce a final product of good flow properties and stability to storage.
- phase-ll sodium tripolyphosphate When phase-ll sodium tripolyphosphate is used, the hydration is found to proceed very reluctantly and to be accompanied by a low viscosity increase. This means rather long stirring periods for quantitative hydration of the tripolyphosphate.
- Sodium tripolyphosphate containing phasel undergoes hydration more rapidly than phase-ll and therefore forms the hexahydrate substantially more rapidly, which means shorter stirring periods for the slurry.
- the use of sodium tripolyphosphates containing phase-l is accompanied by a considerable viscosity increase of the slurry, which is the more rapid the higher the phase-l content of the tripolyphosphate.
- the sodium tripolyphosphates customarily used have a phase-l content between 15 and 45 percent.
- the disadvantage associated with this process resides in the fact that the Na,P O has to be used at least partially in the form of material adjusted to have a definite water content of 22.7 percent by weight, corresponding to that of the hexahydrate. Needless to say the production of sodium tripolyphosphate adjusted to have exactly that water content calls for the use of special steps and very specific conditions.
- sodium tripolyphosphate formed at least partially of material with a crystal water content between a maximum or less than 22.7 percent by weight and a minimum of 17.0 percent by weight, can be used for making detergents slurries with constant, low viscosity, in which the sodium tripolyphosphate practically does not hydrolyze, even after prolonged standing.
- the present invention enables the use of sodium tripolyphosphate with a water content variable within a range of about 5.7 percent, which can be produced considerably more readily.
- the sodium tripolyphosphate having a water content such as proposed in accordance with the present invention should be used in a proportion of at least 5 percent by weight, preferably 50 to 100 percent by weight, referred to the total quantity of sodium tripolyphosphate.
- the detergent slurry may contain further condensed and, if desired, anhydrous phosphates, such as sodium pyrophosphate or sodium metaphosphate.
- the detergent slurry which should conveniently contain a total of to 50 percent by weight sodium tripolyphosphate, can be prepared at temperatures between 20 and 90 C., preferably between 40 and 60 C.
