Productoverzicht<\/h3>\n\n<p class=\"\"><strong>Diethylfumaraat<\/strong> (DEF), <strong>CAS-nr. 623-91-6<\/strong> (ook bekend als <strong>fumaarzuurdi\u00ebthylester<\/strong> of <strong>diethyl(E)-butenedioaat<\/strong>) en ethylfumaraat, is een zeer zuivere di\u00ebster van fumaraat gevormd door de reactie van fumaarzuur en ethanol. Deze kleurloze vloeistof is oplosbaar in ethanol, ether, aceton en chloroform, en licht oplosbaar in water. Industrie\u00ebn gebruiken ethylfumaraat op grote schaal als tussenproduct en oplosmiddel in organische synthese, en ze gebruiken het ook als een veelzijdige weekmaker, oppervlaktebedekker en smaakstof. Daarnaast is het een essenti\u00eble grondstof en tussenproduct voor de productie van geneesmiddelen en agrochemicali\u00ebn. Toonaangevende fabrikanten en leveranciers produceren diethylfumaraat in gespecialiseerde fabrieken in China en garanderen een hoge kwaliteit en consistentie die voldoen aan de eisen van verschillende toepassingen.    <\/p>\n\n<p class=\"\">Onze productiefaciliteiten in China garanderen een hoge productiekwaliteit van diethylfumaraat, waarbij een proces van fumaarzuurcondensatie met ethanol wordt gebruikt om de kwaliteit en consistentie te handhaven.<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-2-product-description\">2.
