- N-alkyl phthalamide acid derivative, synthesis method and application thereof
-
The invention discloses an N-alkyl phthalamide acid derivative, a synthesis method and application thereof, belongs to the technical field of thermoplastic vulcanized rubber, and can effectively solvethe problem of easy precipitation of a slipping agent in the existing TPV. A general structural formula of the derivative is shown as the specification, wherein R is an alkyl group. The preparation method comprises the following steps: distilling phthalamide acid and alkylamine which are dissolved in an organic solvent according to a molar ratio of 1:1 under a high-temperature condition, conducting cooling, then performing reduced-pressure suction filtration, and finally conducting drying to obtain a white waxy or yellowish solid N-alkyl phthalamide acid derivative finished product. The synthesized finished product can be used as a slipping agent in TPV, and has the advantages of excellent slipping effect and precipitation resistance in the use process; in addition, the synthesized finished product can also be applied as a slipping agent to plastics, rubber, other thermoplastic elastomers and printing ink, and the slipping and anti-bonding effects are achieved.

- Scaleable two-component gelator from phthalic acid derivatives and primary alkyl amines: Acid-base interaction in the cooperative assembly
-
A series of phthalic acid derivatives (P) with a carbon-chain tail was designed and synthesized as single-component gelators. A combination of the single-component gelator P and a non-gelling additive n-alkylamine A through acid-base interaction brought about a series of novel phase-selective two-component gelators PA. The gelation capabilities of P and PA, and the structural, morphological, thermo-dynamic and rheological properties of the corresponding gels were investigated. A molecular dynamics simulation showed that the H-bonding network in PA formed between the NH of A and the carbonyl oxygen of P altered the assembly process of gelator P. Crude PA could be synthesized through a one-step process without any purification and could selectively gel the oil phase without a typical heating-cooling process. Moreover, such a crude PA and its gelation process could be amplified to the kilogram scale with high efficiency, which offers a practical economically viable solution to marine oil-spill recovery.
