-
Paragraph 0039-0042, (2020/07/12)
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.

The synthesis of a series of sodium monoalkylamide phthalate surfactants is described, and the surface activity properties of the surfactants are reported. The mono-alkylamide phthalic acids were synthesized by amidation using primary aliphatic amines (lauryl, myristyl, cetyl) and phthalic anhydride as starting material. They were structurally characterized by IR, 1H NMR and MS. The sodium mono-alkylamide phthalate surfactants were prepared by neutralization of the precursor acids with sodium hydroxide. They reduced the surface tension of water to 30-38 mN m-1 at concentration levels of 10-4 mol L-1. AOCS 2012.
Organic acids as catalysts for the erosion of polymers
-
, (2008/06/13)
The invention relates to the use of carboxylic acids incorporated as a catalyst in poly(orthoester)s and other acid labile polymers such that upon exposure to aqueous environments the acid catalyzes the erosion of the polymer matrix. The rate of release of a drug substance incorporated into or surrounded by the poly(orthoester) or other acid labile polymer can be controlled in that the drug is released as the polymer is eroded in response to the catalytic action of the acid incorporated therein.
