Di(2-ethylhexyl) adipate*
Di(2-ethylhexyl) adipate [bis(2-ethylhexyl) adipate, DEHA, octyl adipate, dioctyl adipate, DOA, CAS No. 103-23-1], a plasticizer added to vinyl plastics to give low temperature flexibility, is dispersed (not bound) in the polymer chain matrix. Approved by the U.S. Food and Drug Administration for use in plastics that may contact nonfatty, nonalcoholic foods (not to exceed 24% by weight of the p...
متن کاملBis(2-phenylbiguanidium) adipate tetrahydrate
In the title salt, 2C(8)H(12)N(5) (+)·C(6)H(8)O(4) (2-)·4H(2)O, the anion is located on a centre of symmetry. The observed supra-molecular network of the crystal structure is produced by ten different hydrogen bonds of the N-H⋯N, N-H⋯O and O-H⋯O types. One additional O-H group is not connected to an acceptor site.
متن کاملA CONVENIENT SYNTHESIS OF MACROCYCLIC DIAMIDES
Some new macrocyclic dibenzotrioxadiamides, dibenzotetraoxadiamide, dibenzopentaoxadiamide, dibenzothiatrioxadiamide, tribenzotrioxadiamides and tetrabenzohexaoxadiamide (14-21), (26) and (27) have been prepared. These compounds were obtained in the macrocyclization step by reacting the diamine (4) with appropriak dicaxboxylic acid dichlorides (5-13) and (24). The cyclization does not requ...
متن کاملIntertwining lamellar assembly in porous spherulites composed of two ring-banded poly(ethylene adipate) and poly(butylene adipate).
Poly(1,4-butylene adipate) (PBA) and poly(ethylene adipate) (PEA), each with the ability to form ring-banded morphologies at same Tc, were simultaneously crystallized from mixtures of various compositions. Investigations on morphology, phase and thermal behavior were conducted in order to reveal lamellar packing and spherulitic structures in this binary system. As PBA is faster-crystallizing an...
متن کاملMacrocyclic complexes: synthesis and characterization
A no vel series of co mplexes of the type [M(C28H24N4)X]X2, where M = Cr(III), Fe(III) or Mn(III), X = Cl−, NO3, CH3COO and (C28H24N4) corresponds to the tetradentate macrocyclic ligand, were synthesized in methanolic media by the template condensation of 1,8-diaminonaphthalene and 2,3-butanedione (diacetyl) in the presence of trivalent metal salts. The complexes were characterized by elemental...
