For the cure study on the alumina trihydrate reinforced allylester resins, three kinds of allylester prepolymer have been synthesized through transesterification using diallyl terephthalate + 1,3-butylene glycol, diallyl isophthalate + 1,3-butylene glycol, and diallyl isophthalate + diethylene glycol
. Subsequently, DSC dynamic curing experiments have been carried out to estimate the activation energy (E) and the frequency factor (A) of cured allylester resins (20-23).
He noted that the export products of South Pars region include light and heavy polyethylene, diethylene glycol
, triethylene glycol, monoethylene glycol, urea fertilizer, butane, propane, gas condensates, cement and methanol.
The cosolvents used were: ethylene glycol monobutyl ether (EB, a fast hydrophilic); diethylene glycol
mono butyl ether (DB, a slow hydrophilic); and dipropylene glycol normal butyl ether (DPnB, a slow hydrophobic).
Six more child deaths were recorded on Wednesday, on top of 28 reported last month in three locations after being given "My Pikin", a teething syrup contaminated with diethylene glycol
, which is blamed for causing kidney failure.
All had traces of diethylene glycol
, according to the Ministry of Commerce and Industry.
The RAPEX system recently showed its effectiveness in the case of a Chinese toothpaste that contained diethylene glycol
, a toxic substance that can be used as antifreeze or solvent.
These toothpastes may contain diethylene glycol
, a chemical used in antifreeze.
distearate, isopropyl myristate, and isopropyl palmitate are generally compatible with cellulose nitrate and ethyl cellulose.
Ether ester plasticizers based on ethylene glycol monobutyl ether and diethylene glycol
monobutyl ether are listed in Section 313 of SARA Title Ill by the EPA.
In an engaging style, Fielden tells us about frauds concerning Monsieur Grivelet (Burgundy), Austria (diethylene glycol
) and Monsieur Bert (Bordeaux).
