Preparation method of higher fatty alcohol 2-alkoxy ethanol

The invention provides a preparation method of higher fatty alcohol 2-alkoxy ethanol, and relates to the technical field of organic synthesis, higher fatty alcohol and sulfonyl halide are used as raw materials for cascade reaction, the higher fatty alcohol is completely converted into sulfonate under the action of alkali, and then the sulfonate is subjected to phase transfer reaction under the promotion of a phase transfer catalyst (the used phase transfer catalyst comprises quaternary ammonium salt or crown ether), sulfonate directly performs nucleophilic substitution reaction with ethylene glycol, and the reaction temperature is controlled to complete the reaction within half an hour to obtain the corresponding higher fatty alcohol 2-alkoxy ethanol. The method is low in raw material and reagent cost, simple in process operation, small in pollution, high in product yield and purity, and suitable for large-scale preparation.

Combinatorial synthesis of PEG oligomer libraries

A simple chain-extending approach was established for the scale-up of the monoprotected monodisperse PEG diol materials. Reactions of THP-(OCH2CH2)n—OMs (n=4, 8, 12) with a large excess of commercially available H—(OCH2CH2)n—OH (n=1-4) under basic conditions led to THP-(OCH2CH2)n—OH (n=5-15). Similarly, Me-(OCH2CH2)n—OH (n=4-11, 13) were prepared from Me-(OCH2CH2)n—OMs (n=3, 7, 11). For the chain elongation steps, 40-80% yields were achieved through extraction purification. PEG oligomer libraries I and II were generated in 50-95% overall yields by alkylation or acylation of THP-(OCH2CH2)n—OH (n=1-15) followed by deprotection. Alkylation of Me-(OCH2CH2)n—OH (n=1-11, 13) with X—(CH2)m—CO2R (X=Br or OMs) and subsequent hydrolysis led to PEG oligomer library III in 30-60% overall yields. Combinatorial purification techniques were adapted to the larger-scale library synthesis. A total of 498 compounds, each with a weight of 2-5 g and a minimum purity of 90%, were synthesized.

Synthesis of glycol ethers and their use for intensification of oil recovery

Monoalkyl ethers of ethylene and triethylene glycols were prepared and tested for intensification of oil recovery. The features of oil displacement with aqueous solutions of glycol ethers from bulk models of strata and the effect of glycol ethers on acid treatment of oil-saturated samples were examined. A correlation between the structure of ether and its performance was revealed. The interphase tension at the boundary between the aqueous solution of the glycol ether and kerosene was determined.
