This valuable compound is produced in standard conditions as a <strong>completely transparent, bright, and odorless liquid<\/strong>. Its most prominent physicochemical characteristic is its <strong>complete miscibility with water in any proportion<\/strong>, providing extraordinary flexibility in industrial processes. The presence of two hydroxyl groups (-OH) and an ether linkage (-O-) in its molecular structure makes DEG a <strong>powerful polar solvent, an effective humectant, and a key intermediate<\/strong> in the production chain of resins and polymers.<\/p>\n<p><strong>MizanPetroGas Company<\/strong> supplies Diethylene Glycol with guaranteed quality, sourced directly from <strong>Shazand Petrochemical (Arak)<\/strong> and <strong>Marun Petrochemical<\/strong>, offered in <strong>Bulk<\/strong> and <strong>new 220-liter drums<\/strong> (4 strapped drums per wooden pallet).<\/p>\n<div class=\"mpg-box\"><strong>MizanPetroGas | <a href=\"https:\/\/wa.me\/989155118932\" style=\"color:var(--brand);text-decoration:none;\">09155118932<\/a> | sell@mizanpetrogas.com<\/strong><\/div>\n<h2>Pricing and Purchasing Diethylene Glycol (DEG)<\/h2>\n<p>The price of DEG in global markets is a function of <strong>ethylene and ethylene oxide feedstock prices<\/strong>, <strong>global MEG rates<\/strong>, <strong>shipping and logistics costs<\/strong>, and <strong>exchange rate fluctuations<\/strong>. Given domestic production at Shazand and Marun petrochemicals, this product enjoys a <strong>price competitive advantage<\/strong> in the Iranian market. Direct and bulk purchasing from <strong>MizanPetroGas<\/strong> eliminates intermediaries, providing <strong>competitive pricing<\/strong>, <strong>quality assurance<\/strong>, and <strong>sustainable supply planning<\/strong> for industrial consumers. Contact our experts to inquire about daily prices.<\/p>\n<h2>Technical Overview<\/h2>\n<p>Diethylene Glycol is a member of the <strong>glycols (diols) family<\/strong> and an intermediate product in the ethylene glycol manufacturing process. Its molecular structure includes <strong>two terminal hydroxyl groups<\/strong> separated by an <strong>ether bridge ($-CH_{2}-O-CH_{2}-$)<\/strong>. This unique structure gives DEG dual properties: on one hand, <strong>high polarity and excellent water solubility<\/strong> (due to OH groups and hydrogen bonding), and on the other hand, <strong>molecular flexibility and controlled viscosity<\/strong> (due to the ether linkage).<\/p>\n<p>DEG&#8217;s high boiling point (around 245\u00b0C) and extremely low vapor pressure (&lt; 0.01 kPa at 25\u00b0C) make it a <strong>safe and stable<\/strong> option for high-temperature processes. Its strong <strong>hygroscopic (moisture-attracting)<\/strong> property also turns DEG into an <strong>ideal humectant and desiccant<\/strong> across various industries. The reactivity of the two OH groups allows DEG to be used as a <strong>diol monomer<\/strong> in the synthesis of polyesters and polyurethanes.<\/p>\n<h2>Key Features<\/h2>\n<ul
