127544-88-1 - Introduction
N,N-bis (4-sulfobutyl)-3-methylaniline disodium salt (SDBS) is an organic compound. Its chemical formula is [C6H4(CH3)NH2]2 · Na2SO3, which is an organic acid salt. The following is a description of the nature, use, formulation and safety information of SDBS:
1. nature:
(a) Appearance: Colorless to light yellow crystalline or powdery solid.
(B) Solubility: Soluble in water, slightly soluble in alcohol solvents, almost insoluble in organic solvents.
(c) pH: about 8-9.
(d) Melting point: about 280-290°C.
2. use:
(a) Surfactant: SDBS is a non-ionic surfactant that can be used in detergents, emulsifiers, preservatives, etc.
(B) additives: can be used as colloidal stabilizers, dispersants, thickeners and other applications in cosmetics, textiles, pigments and other fields.
(c) Laboratory reagents: In chemical experiments, SDBS is commonly used for analysis and dispersion of precipitates.
3. Preparation method:
The preparation of SDBS is generally obtained by reacting benzylamine with sodium sulfite. The specific steps are to dissolve benzylamine in water, then slowly add sodium sulfite solution to react, filter to remove impurities, and finally purify by crystallization to obtain crystalline solid.
4. Safety Information:
SDBS is a relatively safe compound under general conditions of use. However, long-term exposure or swallowing may have health effects. It is recommended to avoid contact with skin and eyes during use, and to ensure that the operation is carried out in a well-ventilated place. In case of accidental contact or ingestion, seek medical advice immediately.
