Embodiment 1

[0020] Synthesis of Fluorinated Alkoxycyclotriphosphazene Derivatives:

[0021] Add 1000 mL of tetrahydrofuran and 232 g of octafluoropentanol into a 2L three-necked flask equipped with a mechanical stirring device, and stir to dissolve. Weigh 26g of sodium metal, cut into small particles, and add 1g of each batch to the octafluoropentanol / tetrahydrofuran solution in batches. After the previous batch of sodium metal disappears completely, add the second batch until all the sodium metal is completely Add, and continue to stir for 1 hour, so that the reaction of the sodium metal is basically complete, and a tetrahydrofuran solution of sodium octafluoropentoxide is obtained.

[0022] Add 500mL of tetrahydrofuran and 58g of hexachlorocyclotriphosphazene into a 3L three-neck flask equipped with a mechanical stirring device, a reflux condenser and a constant pressure addition funnel, and stir until the hexachlorocyclotriphosphazene is completely dissolved. The sodium octafluoropent...

[0031] Synthesis of Fluorinated Alkoxycyclotriphosphazene Derivatives:

[0032] Add 1000mL of tetrahydrofuran and 264g of tetrafluoropropanol into a 2L three-necked flask equipped with a mechanical stirring device, and stir to dissolve. Weigh 52g of sodium metal, cut into small particles, and add 1g per batch to the tetrafluoropropanol / tetrahydrofuran solution in batches. After the previous batch of sodium metal disappears completely, add the second batch until all the sodium metal is completely After adding, continue to stir for 1h to make the sodium metal completely react to obtain a tetrahydrofuran solution of sodium tetrafluoropropoxide.

[0033] Add 700mL of tetrahydrofuran and 116g of hexachlorocyclotriphosphazene into a 3L three-necked flask equipped with a mechanical stirring device, a reflux condenser and a constant pressure addition funnel, and stir until the hexachlorocyclotriphosphazene is completely dissolved. The sodium tetrafluoropropoxide / tetrahydrofuran solut...

Abstract

The invention discloses a fluorine-containing alkoxy ring triphosphonitrile derivative and a preparing method thereof, belonging to the technical field of macromolecule synthesis and textile finishing, and the derivative is used for a multifunctional finishing agent of textile. The method takes fluorine-containing alcohol as a material for reacting with hexachlor ring triphosphonitrile for substitution to synthesize the fluorine-containing alkoxy ring triphosphonitrile derivative; and the fluorine-containing alkoxy ring triphosphonitrile derivative is emulsified by choosing a suitable emulsifier and optimizing emulsion formula, thus obtaining the multifunctional finishing agent of textile with good stability. By adopting the finishing process of rolling-baking-toasting, the textile after finishing has not only good flame-retardant finishing effect but also certain water proof and oil proof effect owning to the introduction of fluoride in the phosphonitrile flame retardant.

Description

technical field [0001] The present invention relates to the synthesis and application of a fluorine-containing compound, in particular to a fluorine-containing alkoxycyclotriphosphazene derivative and its preparation method, and its application to the preparation of a multifunctional finishing agent for textiles, which belongs to high Technical field of molecular synthesis and textile finishing. Background technique [0002] The number of fires caused by textiles and the harm to personal safety are more serious than fires caused by other reasons. For a long time, both at home and abroad have attached great importance to the research and product development of flame retardant textiles. The production and consumption of flame retardants abroad have reached a considerable scale, while the development of flame retardants in my country is relatively late. [0003] At present, the organic flame retardants used in my country include halogen and phosphorus. Among them, phosphorus-...
