Paragraph 0018; 0019; 0020, (2018/11/22)
The invention discloses a preparation method of a hexafluoropropylene dipolymer. The method comprises the steps that preheated hexafluoropropylene gas is introduced into a reaction container filled with alkyl hexamethylenetetramine fluorine salts show as a formula (IV); continuous reaction is performed under the heating and stirring conditions; reaction products are treated to obtain the hexafluoropropylene dipolymer; in the formula (IV) shown in the description, R is an alkyl group with the carbon number being 1 to 10. The preparation method is used as a novel reaction route; the condition that catalysts and solvents are used for polymerization reaction in a traditional process is avoided; the preparation process is simple; the equipment requirements are low; the reaction conditions are mild.
Methylhexamethylenetetramine fluoride dihydrate: A new fluorodenitration reagent

, p. 91 - 93 (2007/10/03)
Methylhexamethylenetetramine fluoride dihydrate has been prepared by conventional methods. It is moderately soluble in polar aprotic solvents, and shows good thermal stability, enabling it to be dried. The reagent is capable of converting activated nitroaromatics to the corresponding fluoroaromatics, with a high selectivity to monofluorodenitration being observed with some polysubstituted aromatics.
