Technical Introduction<\/h3>\n

Linear Alkyl Benzene Sulphonic Acid (LAS), also referred to as Linear Dodecyl Benzene Sulphonic Acid (LDBSA) for the most common C\u2081\u2082 alkyl chain variant, is a high-volume\u00a0anionic surfactant precursor. It is a key raw material for the production of household detergents, industrial cleaners, and textile auxiliaries, valued for its excellent detergency, emulsification, and wetting properties.<\/p>\n

Item<\/td>\nTechnical Specification<\/td>\n<\/tr>\n
Chemical Name<\/td>\nLinear Alkyl Benzene Sulphonic Acid<\/td>\n<\/tr>\n
Abbreviation<\/td>\nLAS; LDBSA (for C\u2081\u2082 alkyl chain grade)<\/td>\n<\/tr>\n
General Molecular Formula<\/td>\nR-C6<\/sub>H4<\/sub>-SO3<\/sub>H\u00a0(where\u00a0R\u00a0= linear alkyl chain of\u00a0C10<\/sub>\u2013C13<\/sub>;\u00a0C12<\/sub>\u00a0is the dominant industrial grade)<\/td>\n<\/tr>\n
Peso molecular<\/td>\n326.48 g\/mol (for\u00a0C12<\/sub>\u00a0alkyl chain variant)<\/td>\n<\/tr>\n
CAS Registry Number<\/td>\n27176-87-0 (generic for\u00a0C10<\/sub>\u2013C13\u00a0<\/sub>LAS)<\/td>\n<\/tr>\n
UN Number<\/td>\n2584 (Class 8: Corrosive Substances)<\/td>\n<\/tr>\n
Structural Feature<\/td>\nConsists of a hydrophobic linear alkyl chain attached to a benzene ring, with a hydrophilic sulfonic acid group (-SO3<\/sub>H) on the benzene ring. The linear alkyl structure ensures high biodegradability compared to branched alkyl benzene sulfonic acids.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

2. Core Industrial Applications<\/h4>\n

LAS is the foundational raw material for anionic surfactants, with applications spanning household and industrial sectors:
\nHousehold Detergents (Largest Application)<\/strong>
\nNeutralized with sodium hydroxide (NaOH), potassium hydroxide (KOH), or ethanolamine to produce\u00a0sodium linear alkyl benzene sulfonate (LAS-Na)\u00a0or potassium alkyl benzene sulfonate\u2014key ingredients in laundry powders, liquid detergents, dishwashing liquids, and soap bars. These derivatives deliver excellent dirt-dissolving and emulsifying performance, even in hard water.<\/p>\n

Industrial Cleaning Agents<\/strong>
\nFormulated into heavy-duty degreasers, metal cleaning fluids, and industrial laundry detergents. LAS-based cleaners are effective at removing oil, grease, and particulate contaminants from machinery, textiles, and hard surfaces.<\/p>\n

Textile & Leather Industry<\/strong>
\nUsed as a wetting agent, emulsifier, and dyeing auxiliary in textile processing. It improves the penetration of dyes and chemicals into fibers, enhancing color uniformity and fabric quality. It also serves as a degreasing agent for leather tanning.<\/p>\n

Agricultural Chemicals<\/strong>
\nActs as an emulsifier in pesticide formulations (e.g., herbicides, insecticides), improving the dispersion and adhesion of active ingredients on crop surfaces, thereby boosting pesticide efficacy.<\/p>\n

Other Uses<\/strong>
\nRaw material for emulsion polymerization (e.g., in the production of latex and plastics); component of water treatment flocculants; additive in personal care products (e.g., shampoos, body washes).<\/p>\n

3.Transport:<\/strong> Comply with UN 2584 transport regulations for Class 8 corrosive substances. Use leak-proof, corrosion-resistant containers. Label packages clearly with “CORROSIVE” warnings. Avoid transport in extreme temperatures or humid conditions.<\/p>","protected":false},"excerpt":{"rendered":"
