O etilenoglicol \u00e9 o \u00e1lcool di-h\u00eddrico alif\u00e1tico mais simples, com propriedades qu\u00edmicas dos \u00e1lcoois, como a capacidade de gerar \u00e9ter, \u00e9ster ou ser oxidado em \u00e1cido ou alde\u00eddo, bem como ser condensado para formar \u00e9ter ou ser substitu\u00eddo por halog\u00e9neo. A sua rea\u00e7\u00e3o com cloreto de acilo ou anidrido \u00e1cido forma geralmente di\u00e9steres. Sob aquecimento na presen\u00e7a de catalisador (di\u00f3xido de mangan\u00eas, \u00f3xido de alum\u00ednio, \u00f3xido de zinco ou \u00e1cido sulf\u00farico), pode sofrer desidrata\u00e7\u00e3o intermolecular ou intramolecular para formar os acetais c\u00edclicos de etileno, que podem reagir com \u00e1cido n\u00edtrico para gerar dinitrato de glicol (um explosivo). O etileno glicol \u00e9 a mat\u00e9ria-prima para a produ\u00e7\u00e3o de resinas de poli\u00e9ster, resinas alqu\u00eddicas e fibras de poli\u00e9ster. Pode tamb\u00e9m ser utilizado como agente refrigerante para motores de autom\u00f3veis e avi\u00f5es. Em 1980, a quantidade de glicol utilizada como agente refrigerante \u00e9 igual \u00e0 quantidade consumida para a produ\u00e7\u00e3o de poli\u00e9ster. Al\u00e9m disso, tamb\u00e9m pode ser utilizado para sintetizar pol\u00edmeros como as fibras de poli\u00e9ster. O dinitrato de etilenoglicol, quando utilizado em combina\u00e7\u00e3o com nitroglicerina, pode reduzir o ponto de congela\u00e7\u00e3o dos explosivos. O etilenoglicol tamb\u00e9m pode ser utilizado como mat\u00e9ria-prima de produtos farmac\u00eauticos, pl\u00e1sticos e solventes de alto ponto de ebuli\u00e7\u00e3o. A ind\u00fastria utiliza o etileno como mat\u00e9ria-prima, convertendo-o primeiro em \u00f3xido de etileno e hidrolisando-o depois para produzir etilenoglicol.<\/p>","protected":false},"featured_media":4310,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[22],"product_tag":[24],"class_list":{"0":"post-4259","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-daily-chemicals","7":"product_tag-daily-chemicals","9":"first","10":"instock","11":"shipping-taxable","12":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product\/4259","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/comments?post=4259"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/media\/4310"}],"wp:attachment":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/media?parent=4259"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product_brand?post=4259"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product_cat?post=4259"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product_tag?post=4259"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
