Behind many finished chemical products—from fabric softeners to oilfield additives—lie the essential intermediates that make them work. Shandong Kerui Chemicals has established itself as a leading manufacturer of tertiary amines, the foundational building blocks for a vast array of downstream products. These high-purity amines serve as the critical raw materials for synthesizing quaternary ammonium salts, amine oxides, and betaines, which are indispensable in dozens of industries .
Kerui’s portfolio of tertiary amines is extensive and tailored to specific application needs. The Alkyl Dimethylamines (DMA series) are key examples. Products like Octyl Dimethylamine (DMA8) and Cocoalkyl Dimethylamine (DMACO) are the primary raw materials for producing cationic surfactants . They can react with benzyl chloride to form benzyl quaternary ammonium salts, with methyl chloride for methyl quaternary salts, or with sodium chloroacetate to create amphoteric betaines—each serving distinct roles in biocides, softeners, and emulsifiers .
For specialized applications, Kerui offers Double-chain methylamines like Dioctyl/Decyl Methylamine (MA810) and DiDodecyl Methylamine (MA1212) . These produce gemini quaternary ammonium salts and double-chain quaternary salts, which are particularly valued in the biocide and disinfectant industries for their enhanced antimicrobial activity . The Oleyl Dimethylamine (DMAO V) is another critical intermediate for synthesizing oilfield and textile chemicals, prized for its high iodine value which indicates its unsaturated nature .
Kerui’s commitment to quality is evident in the stringent specifications for these amines, with high tertiary amine content (often ≥95-97%) and low color (APHA ≤30-60), ensuring high reactivity and purity for downstream synthesis . By supplying these essential building blocks, Kerui Chemical empowers formulators across industries to create high-performance end products, solidifying its role as a key enabler in the global chemical value chain.
