6 results about "Naphthalenesulfonate" patented technology

Naphthalenesulfonates are derivatives of sulfonic acid which contain a naphthalene functional unit. A related family of compounds are the aminonaphthalenesulfonic acids. Of commercial importance are the alkylnaphthalene sulfonates, which are used as superplasticizers in concrete. They are produced on a large scale by condensation of naphthalenesulfonate or alkylnaphthalenesulfonates with formaldehyde.

Methods for determining cell viability

ActiveDE102016121808B4Cell membraneFluorescence microscope
Method for determining cell viability in a cell culture of biological cells for the biotechnological production of proteins, in particular antibodies, characterized in that a fluorescent dye selected from 4,4'-dianilino-1,1'-binaphthyl-5,5'-disulfonate (Bis-ANS) or 8-anilinonaphthalene-1-sulfonate (ANS) is used as a detection agent, and wherein the fluorescent dye is present in the cell culture at a concentration of 0.1 µM to 10 µM, the fluorescent dye selectively penetrates cells with damaged cell membranes and binds to intracellular proteins, the labeled cells are detected by excitation in the UV range and detection of the fluorescence in the green wavelength range, and the determination of cell viability is carried out using an automated imaging fluorescence microscope.

A hydrophilic-lipophilic balance type coal water slurry additive, a preparation method and application thereof

PendingCN122234846ALiquid carbonaceous fuelsCoal waterSulfonate
This invention provides a hydrophilic-lipophilic balanced coal-water slurry additive, its preparation method, and its application. By weight, the raw materials include: 18-28 parts of gemini-type polyether-modified naphthalene sulfonate, 4-10 parts of zwitterionic nano-hybrid stabilizer, 12-20 parts of sodium lignosulfonate, 6-12 parts of polycarboxylate-based dispersant, 1.5-4 parts of biopolysaccharide rheology modifier, 10-16 parts of low-temperature flowability improver, 2-4 parts of pH adjuster, 2-5 parts of chelating agent, and 35-50 parts of deionized water. The hydrophilic-lipophilic balanced coal-water slurry additive provided by this invention can form an adsorption layer on the surface of coal particles, achieving synergistic dispersion through electrostatic repulsion and steric hindrance. This improves the low-temperature flowability, long-term storage stability, and coal type adaptability of the coal-water slurry, regulates thixotropy, chelates interfering ions, optimizes the effects of each component, and ensures a stable and homogeneous system.

A method for preparing vulcanized natural latex modified asphalt.

This invention belongs to the technical field of asphalt modification materials, specifically relating to a vulcanized natural rubber latex modified asphalt and its preparation method. It is made from the following raw materials in parts by weight: 100 parts base asphalt, 15-20 parts natural rubber latex, 0.18-0.28 parts sulfur (vulcanizing agent), 0.15-0.36 parts silica, 0.075-0.14 parts 2,6-di-tert-butyl-4-methylphenol (antioxidant), 0.09-0.16 parts zinc ethylphenyl dithiocarbamate, 0.045-0.08 parts 2-mercaptobenzothiazole, 0.075-0.14 parts zinc oxide, and 0.015-0.06 parts naphthalenesulfonate formaldehyde condensate. This invention first vulcanizes the natural rubber latex, significantly improving its elasticity, toughness, and anti-aging properties. Then, it is used for asphalt modification, ultimately producing vulcanized natural rubber latex modified asphalt with excellent low-temperature toughness and high-temperature deformation resistance.
