Introduction of CAS:119438-10-7 | POLY(ETHYLENE GLYCOL) 4-NONYLPHENYL 3-SULFOPROPYL ETHER, POTASSIUM SALT

Synthesis Analysis

The synthesis of triethylene glycol involves several methods. One approach described in the literature involves the reaction of epoxy ethane and water or glycol by step reaction. This method is a key process for producing polyethylene glycols, including triethylene glycol, with specific emphasis on synthesizing glycol using formaldehyde as a raw material (Yuqing, 2005). Another innovative approach involves the use of triethylene glycol with catalytic quantities of zinc chloride under controlled microwave irradiation, demonstrating its efficiency in sensitive Fischer synthesis (Lipińska & Czarnocki, 2006).

Molecular Structure Analysis

Triethylene glycol consists of three ethylene glycol units connected by ether linkages. The molecular structure of TEG facilitates its interaction and binding with various substances, contributing to its diverse applications in different chemical processes.

Chemical Reactions and Properties

TEG participates in a range of chemical reactions due to its functional groups and molecular structure. For instance, an improved synthesis method for triethylene glycol-substituted compounds was developed, showing the versatility of TEG in various synthetic routes (Jia et al., 2020). Additionally, TEG has been used in the synthesis of antioxidants and other functional materials, indicating its utility in creating chemically active and stable compounds.

Research Application of CAS:119438-10-7 | POLY(ETHYLENE GLYCOL) 4-NONYLPHENYL 3-SULFOPROPYL ETHER, POTASSIUM SALT

Chemical Coordination Clusters: TEG is used in Fe/Ln chemistry to create tetranuclear coordination clusters with defect-dicubane cores (Peng, Kostakis, Lan, & Powell, 2013).

Natural Gas Dehydration: It plays a critical role in natural gas dehydration units to prevent gas hydrate formation, pipeline blockage, and liquid water condensation during natural gas transmission (Kamari, Mohammadi, & Bahadori, 2015).

Off-Gas Treatment: It is used to treat off-gas streams containing volatile organic compounds (VOCs), aiding in purifying the off-gas and recovering the VOCs (Sui et al., 2016).

Shale Gas Processing: TEG is used to adjust the water dew point in shale gas processes, impacting CO2 and NOx emissions due to utility consumption and shale gas loss (Li et al., 2019).

Gas Processing Industry: In this industry, TEG is used for glycol dehydration units and occasionally for hydrate inhibition (Wise & Chapoy, 2016).

Oil and Gas Product Desiccation: As a desiccant and dehydrating agent, TEG's moisture content is a crucial quality indicator (Shuan, 2014).

Environmental and Health Concerns: Research also includes studies on TEG's toxicity at high concentrations to cells, its potential contamination, and methods for recycling to reduce production costs (Liu et al., 2017; Lil, 2013; Sorensen et al., 2000).

Enhanced TEG Regeneration: Processes using isooctane and toluene in the natural gas dehydration industry have been explored to boost water volatility and regenerate TEG to higher purity (Paymooni et al., 2011).

Graphene Production: TEG-based reduction of graphite oxide to graphene has been shown to produce high-quality graphene comparable to conventional methods (Mhamane et al., 2012).

Cosmetic Applications: TEG and PEG-4 are used in cosmetic formulations, with studies showing little acute toxicity and no significant reproductive or developmental effects in test animals (International journal of toxicology, 2006).

Petrochemical Wastewater Treatment: The moving bed biofilm reactor (MBBR) can effectively remove TEG from simulated petrochemical wastewater (Bavandpour, Mafigholami, & Khezri, 2018).

Phytoremediation: Echinodorus cordifolius can degrade TEG to diethylene glycol, diethylene glycol to 1,4-dioxan-2-one, or monoethylene glycol, indicating potential for environmental remediation (Teamkao & Thiravetyan, 2015).

Gas Dehydrator Prognostication: Gene Expression Programming (GEP) has been applied to develop mathematical expressions for predicting equilibrium water dewpoint temperature in natural gas dehydrators (Rostami & Shokrollahi, 2017).
