Novel controlled releasing polythiourea microcapsules were prepared from terephthaloyl diisothiocyanate and o-phenylenediamine by interfacial polycondensation.
Two series of thermotropic liquid crystalline polyureas were synthesized by the copolymerization of benzidine (or o-tolidine),1,6-hexane diamine and 2,4-toluene diisocyanate.
According to the ethylene diamine moiety in the structure of some calcium antagonists,we designed and synthesized 5 unreported phenoxybenzamine derivatives.
A detergent for cleaning iron monosulfide was formulated with surfactant, diamino-propadiene, citric and EDTA, and its cleaning mechanism was discussed.
E—M water treatment agent for boilers,composed of ethylenediamine tetramethylene phosphonic acid(EDTMP) and hydrolyzed polymaleic anhydride (HPMA),and its applications are introduced in this article.
Copper conductive adhesives were prepared using epoxy as matrix, the mixture of m-phenylenediamine and diaminodiphenylmethane as hardener, and copper particles as the conducting filler.
A method to measure the content of nickel in the nickel iso - caprylate by complexometric titration using ethylenediamine tetraacetic acid (EDTA) was set up.
When the complex of anhydrous zinc acetate with 1,5-naphthalene diamine was formed, the anhydrous zinc acetate changed from a bidentate ligand to a unidentate ligand.
3, A chelating agent which forms an easily water-soluble metal chelated compound such as nitrilotriacetate (NTA) or ethylene diamine tetraacetate (EDTA) is incorporated in a detergent composition.
