QUAB SPECIALTIES

Solutions of the active substance 3-chloro-2-hydroxypropyl-alkyl-dimethylammonium chloride.

We also offer the Quab Specialties Quab 342, Quab 360 and Quab 426, which are the trade names for the solutions of the active substance 3-chloro-2-hydroxypropyl-alkyl-dimethylammonium chloride. In these products, a methyl group within the quaternary ammonium group is substituted by a long-chain alkyl group (R = dodecyl-, cocoalkyl- or stearyl-). These products are delivered exclusively as chlorohydrins.

Quab 342 and Quab 360 are sold as aqueous solutions with total active weight concentrations of approx. 40 % (chlorohydrin).

Quab 426 is sold as a solution in a 1,2-propanediol / water mixture with approx. 40 % weight concentration (chlorohydrin)

Aqueous chlorohydrin solutions are stable and therefore storable at room temperature in a pH range of 2-6 for several years without any detectable loss of activity. At higher temperatures, the pH will be reduced over time. At storage temperatures below 20 °C (Quab 426) and 10 °C (Quab 342 and Quab 360), waxy like solids may crystallize from the solution.

Suitable Materials:
Stainless steel types, 316L and 316TI (DIN 1.4571) are basically suitable for transport containers but are recommended for storage only with restrictions. Pickling of containers and pipes with attention to welds is mandatory. These materials are subject to pitting after prolonged periods of contact and at elevated temperatures. However, since transport containers are not subject to prolonged contact, these materials may be used for Quab Specialties. Plastic containers may be used in all cases.

Degussa recommends a coating for storage tanks made of stainless steel types, 316L and 316TI (DIN 1.4571). Alternatively, fibre reinforced plastic tanks or other coated storage containers may be used. Suitable materials for Quab Specialties include polyester, polyethylene, PVC, heat cured phenolic resins or epoxy resins, neoprene, Buna S and Buna N. Enameled containers and tanks may also be used. Any damage in the coating must be repaired.

Unsuitable Materials:
For Quab Specialties, containers made of boiler plate H II, aluminum (99.5) and stainless steel types, 304L and 321 (DIN 1.4541) are unsuitable. Test samples of stainless steel types, 304L and 321 (DIN1.4541) show pitting.

For detailed safety, handling, and toxicology information, see the corresponding material safety data sheets, which are available upon request.

The substances are corrosive to the eyes and irritating to the skin. Basically the same safety measures for Quab 188 and Quab 151 apply to the Quab Specialties.

Quab 342, Quab 360, and Quab 426 are toxic to fish. Precautions must therefore be taken to prevent this product and its by-products from entering the aquatic environment.

The Quab specialty products have not only cationic but also surface-active properties which are attributable to the long-chain alkyl groups. The dodecyl, cocoalky,l or stearyl groups lend hydrophobic (lipophilic) properties to the polymers modified by these Quab reagents. This may cause foam formation when aqueous solutions are handled, particularly if there is strong mechanical agitation.
