    摘要: A non-linear surfactant, and particularly a non-linear surfactant comprising bi-functionalized molecules or particles having both hydrophobic and hydrophilic groups. The non-linear surfactant includes a nanoparticle template of a rigid molecular structure, wherein the nanoparticle comprises a molecule or a particle that is bi-functionalized with both hydrophilic and hydrophobic groups to obtain an amphiphilic nanoparticle. The template nanoparticle can be used as a surfactant, wetting agent, emulsifier, detergent or other surface active agents or for the preparation of nanoemulsions or dispersions. The non-linear surfactant can provide smaller particle sizes for emulsion suspensions and foams.

    摘要: The present invention relates to a particulate carbon material that can be produced from renewable raw materials, in particular from biomass containing lignin, comprising: a 14C content that corresponds to that of the renewable raw materials, said content being preferably greater than 0.20 Bq/g carbon, especially preferably greater than 0.23 Bq/g carbon, but preferably less than 0.45 Bq/g carbon in each case; a carbon content in relation to the ash-free dry substance of between 60 ma. % and 80 ma. %; an STSA surface area of the primary particles of at least 5 m2/g and at most 200 m2/g; and an oil absorption value (OAN) of between 50 ml/100 g and 150 ml/100 g. The present invention also relates to a method for producing said carbon material and to the use thereof.

    摘要: The disclosure discloses preparation and application of an alkylcyclohexanol polyoxyethylene ether emulsifier, and belongs to the technical field of surfactants. By performing ethylene oxide adducting on alkylcyclohexanol polyoxyethylene ether (1-3) and using a strong alkaline suspension dispersed in the solvent and alkylcyclohexanol polyoxyethylene ether (1-3) as a catalyst, nonionic surfactants alkylcyclohexanol polyoxyethylene ether (5-17) are synthesized. The products all have good characteristics of nonionic surfactants, and contain lower content of polyethylene. The products such as nonylcyclohexanol ethoxylate (7) and nonylcyclohexanol ethoxylate (9) have emulsifying properties similar to the emulsifying property of nonylphenol ethoxylate (10), and therefore can substitute for nonylphenol ethoxylate (10) as an emulsifier.
