Description
Technical field
The present invention relates to a kind of preparation method of the different hexadecyl ester base oil of carbonic acid two.
Background technology
With the improvement of living standards with industrialized development, lubricant is in the field such as industrial and civilian using wider
General plays indispensable key player.And the infiltration due to lubricant, leakage, overflow and deal with improperly, inevitably
Environment and the ecological balance are damaged.At present, global warming, the big model of serious haze weather take place frequently, and environment sternness situation is to warp
Ji society, people's health all constitute grave danger, and meeting the low-carbon green lubricant of recycling economy and sustainable development turns into
The main direction of studying of novel lubricant.Dialkyl carbonate is that a kind of green lubrication agent is with dimethyl carbonate and mixing fat
Fat alcohol carries out what ester exchange reaction was prepared, and dimethyl carbonate can be by methanol and CO, prepared by carbon, therefore, dialkyl carbonate
Ester is to utilize C0, a kind of effective way of this greenhouse gases, with development in science and technology, or in the future containment Global Greenhouse Effect,
Environmental protection and the maintenance ecological balance provide a kind of positive solution.It is similar with conventional carboxylic acid's ester (such as dibasic acid esters, polyol ester),
Dialkyl carbonate is biodegradable and no biotoxicity：The highly polar of ester group makes it easily be adsorbed in metal surface, and lubricity is strong：
There is good compatibility, excellent combination property with polymer.And the special molecular structure that dialkyl carbonate has, gather around it
There are the thermo oxidative stability and hydrolysis resistance more prominent than carboxylate.Need it is emphasized that dialkyl carbonate heat point
Acidic components are not produced after solution, therefore corrosive wear will not be caused also not cause detergent for lubricating oil because of acidic components, disperse
The failure of the additives such as agent, antioxidant.At present, carbonic ester work has been carried out in the researcher of the state such as China, Italy, Germany
For lubricant exploration based on carbonic ester oil be prepared for each class lubricating oil such as spinning oil, engine oil, refrigerator oil, liquid
Force feed etc..Because dialkyl carbonate is biodegradable and excellent combination property.People also increasingly pay close attention to it and led in green lubrication
The application ester exchange reactions mild condition in domain, technological process are short and not high to equipment requirement, therefore, with dimethyl carbonate
(DMC) it is raw material with Long carbon chain fatty alcohol, is received significant attention by the method for ester exchange synthesis of dialkyl carbonates.
