This compound is also resistant to oxidation by catalysts such as hydrogen peroxide. The dimethyl terephthalate molecule is made up of two methyl groups (CH3) and two ethyl groups (C2H5) attached to a central carbon atom with four bonds. Dimethyl terephthalate is produced by reacting ethylene glycol with terephthalic acid in an esterification reaction.<\/p>\n<p>The addition of a catalyst can lead to an increase in the rate of this reaction. Methyl ethyl terephalate, an ester formed from the reaction between methyl alcohol and terephtalic acid, has been shown to produce high levels of ethanol and CO emissions when heated at high temperatures.<\/p>\n<h2>Chemical Identity<\/h2>\n<p><strong>Common name:<\/strong> Dimethyl terephthalate (DMT)<br \/>\n<strong>Kimyasal ad\u0131:<\/strong> Dimethyl terephthalate<br \/>\n<strong>IUPAC name:<\/strong> Dimethyl benzene-1,4-dicarboxylate<\/p>\n<p><strong>E\u015f anlaml\u0131lar:<\/strong><\/p>\n<ul>\n<li>Terephthalic Acid Dimethyl Ester<\/li>\n<li>1,4-Benzenedicarboxylic acid, dimethyl ester<\/li>\n<li>Dimethyl p-phthalate<\/li>\n<li>Dimethyl 4-phthalate<\/li>\n<li>Dimethyl 1,4-benzenedicarboxylate<\/li>\n<\/ul>\n<p><strong>CAS Registry Number:<\/strong> 120-61-6<br \/>\n<strong>PubChem CID:<\/strong> 8441<\/p>\n<p><strong>MDL No:<\/strong> MFCD00008440<\/p>\n<p><strong>Molek\u00fcler form\u00fcl:<\/strong> C\u2081\u2080H\u2081\u2080O\u2084<br \/>\n<strong>Molek\u00fcl a\u011f\u0131rl\u0131\u011f\u0131:<\/strong> 194.18 g\/mol<br \/>\n<strong>InChIKey:<\/strong> WOZVHXUHUFLZGK-UHFFFAOYSA-N<br \/>\n<strong>SMILES:<\/strong> COC(=O)C1=CC=C(C=C1)C(=O)OC<\/p>\n<p>Documentation on Specification, MSDS, TSE \/ BSE Statement and Retest Statement upon request.<\/p>","protected":false},"featured_media":30842,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[82],"product_cat":[1218],"product_tag":[1225,1222,1221,1224,1219,1220,1228,1226,1223,1227],"class_list":["post-30835","product","type-product","status-publish","has-post-thumbnail","product_brand-research-chemical","product_cat-aromatic-esters","product_tag-analytical-chemistry","product_tag-aromatic-esters","product_tag-cas-120-61-6","product_tag-chemical-reference","product_tag-dimethyl-terephthalate","product_tag-dmt","product_tag-laboratory-chemicals","product_tag-materials-chemistry","product_tag-organic-chemistry","product_tag-polymer-research","first","instock","taxable","shipping-taxable","purchasable","product-type-variable"],"_links":{"self":[{"href":"https:\/\/purematrixchem.com\/tr\/wp-json\/wp\/v2\/product\/30835","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/purematrixchem.com\/tr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/purematrixchem.com\/tr\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/purematrixchem.com\/tr\/wp-json\/wp\/v2\/comments?post=30835"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/purematrixchem.com\/tr\/wp-json\/wp\/v2\/media\/30842"}],"wp:attachment":[{"href":"https:\/\/purematrixchem.com\/tr\/wp-json\/wp\/v2\/media?parent=30835"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/purematrixchem.com\/tr\/wp-json\/wp\/v2\/product_brand?post=30835"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/purematrixchem.com\/tr\/wp-json\/wp\/v2\/product_cat?post=30835"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/purematrixchem.com\/tr\/wp-json\/wp\/v2\/product_tag?post=30835"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
