- Description:
Product Name: Linear Alkylbenzene
CAS No.:27176-87-0
MF: C6H6CnH2n-1（n=10-13）
EINECS No.: 248-289-4
- Characteristics:
Linear alkylbenzene is colorless or slightly yellow transparent, no suspended liquid, refractive index (n20D) 1.4800~1.4900, relative density 0.8500~0.8700, average molecular weight 220~270, Enshi distillation range 265~350 °C. Its chemical properties are stable. The flash point is above 100 ° C; it is easy to sulfonate with fuming sulfuric acid or SO3 to form alkylbenzene sulfonic acid. It is currently the most important raw material for domestic consumer detergent products. Various household detergents produced by industrial linear alkylbenzene have the characteristics of strong detergency, good bactericidal effect, no residue and no pollution.
