Embodiment 1

[0053] Embodiment 1: the synthesis of the hybrid type nonionic fluorosurfactant containing sodium ion

[0054] Add polymerized glycerin and perfluoro or fluorinated alkyl carboxylic acid with 4 to 16 carbon atoms into the reactor in an equimolar ratio or a ratio of 1.5:1, and stir under negative pressure at 140°C to 200°C under nitrogen protection carry out esterification reaction. When the reaction temperature reaches above 120°C, start to monitor the pH value of the reactant. When the pH value reaches 3.5, stop heating to slow down the esterification reaction. Slowly add NaHCO in batches when the temperature is lowered to 120°C 3 Aqueous solution, continue to monitor the pH value to 6.5±0.5, stop adding liquid caustic soda NaHCO 3 , the product is C n f 2n+1 The anionic fluorosurfactant of COONa continued to react for 30 minutes and was regarded as the end point. Then cool down to 60°C naturally under stirring to discharge the material. This period of time can promote ...

Abstract

The invention relates to a hybridized non-ionic fluorin surface activator and relative preparing method. Said invention is formed by two parts: the main part is the non-ionic fluorin surface activator which uses polycondensation polyatomic alcohol as hydrophilic group with hydrophilic hydroxyl group (-OH); said part is full-fluorin or fluorin acrylic carboxyl acid polyglycerol. The invention can avoid uses polyoxyethylene chain as hydrophilic group in present technique, to build large hydrophilic group main chain, while the polyoxyethylene chain will generate cloud point caused by temperature change. And another part is carboxylate anion fluorin surface activator used to hybridize non-ionic surface fluorin activator. And said method uses the character that the base electrodes of molecules of said two parts are different to hybridize molecule with Van der Waals force.

Description

technical field [0001] The patent of the invention belongs to chemical preparations, in particular to a novel hybrid non-ionic fluorine surfactant belonging to organic compounds of non-metal elements and its synthesis method. Background technique [0002] Among the existing fluorine-containing surfactant products, there are many ionic products and few non-ionic products. Among non-ionic fluorosurfactants, polyoxyethylene chains are the main types of hydrophilic groups. So far, there is no report on hybrid nonionic fluorosurfactants. [0003] From the perspective of application fields, the commercial variety of fluorosurfactants is monotonous, the selection range is narrow, and the price is expensive. For example: fire extinguishing agents used in firefighting, after eliminating the halon series products that are harmful to the atmospheric ozone layer, the only ideal product to choose from is AFFF products, which are mainly imported by the 3M company in the United States, a...
