Embodiment 1

[0027] In the first step, n-butanol is pretreated. In the reaction vessel, put 10-20g 3A molecular sieve per 1kg of n-butanol, stir evenly, let it stand for 24 hours to filter out the molecular sieve, then put in the same fresh molecular sieve, repeat this process three times before use.

[0028] The second step is the preparation of intermediates. Put 2Kg of n-butanol and 1.75g ​​of polymetallic catalyst into the reaction kettle, vacuumize to make the pressure reach -0.092MPa; when the temperature does not exceed 40°C, feed nitrogen into the reaction kettle to raise the pressure to 0.1Mpa, and then Vacuumize to reduce the pressure to -0.092MPa, repeat three times, raise the temperature of the reactor to 120-130°C to initiate the reaction; after the reaction, slowly add 7Kg of propylene oxide to the reactor, control the reaction temperature at 140-160°C No more than 0.2 Mpa, and the reaction time is controlled at 1.5 hours; after the dropwise addition, keep warm for 30 minute...

Embodiment 2

[0031] In the first step, n-butanol is pretreated. In the reaction vessel, put 10-20g 3A molecular sieve per 1kg of n-butanol, stir evenly, let it stand for 24 hours to filter out the molecular sieve, then put in the same fresh molecular sieve, repeat this process three times before use.

[0032] The second step is the preparation of intermediates. Put 2.5Kg of treated n-butanol and 2.2g of polymetallic catalyst into the reactor, vacuumize to make the pressure reach -0.092MPa; when the temperature does not exceed 40°C, feed nitrogen into the reactor to raise the pressure to 0.1Mpa, Vacuum again to reduce the pressure to -0.092MPa, repeat three times, raise the temperature of the reactor to 120-130°C to initiate the reaction; after the reaction, slowly add 7.5Kg of propylene oxide to the reactor, and control the reaction temperature at 140-160°C , the pressure does not exceed 0.2 Mpa, and the reaction time is controlled at 1.5 hours; after the dropwise addition, keep warm for ...

Embodiment 3

[0035] In the first step, n-butanol is pretreated. In the reaction vessel, put 10-20g 3A molecular sieve per 1kg of n-butanol, stir evenly, let it stand for 24 hours to filter out the molecular sieve, then put in the same fresh molecular sieve, repeat this process three times before use.

[0036] The second step is the preparation of intermediates. Put 3Kg of treated n-butanol and 3.0g of polymetallic catalyst into the reactor, vacuumize to make the pressure reach -0.092MPa; when the temperature does not exceed 40°C, feed nitrogen into the reactor to raise the pressure to 0.1Mpa, and then Vacuumize to reduce the pressure to -0.092MPa, repeat three times, raise the temperature of the reactor to 120-130°C to initiate the reaction; after the reaction, slowly add 9Kg propylene oxide to the reactor, control the reaction temperature at 140-160°C, No more than 0.2 Mpa, and the reaction time is controlled at 1.5 hours; after the dropwise addition, keep warm for 30 minutes, and the in...

Abstract

The invention provides a synthetic method of water insoluble polyether synthetic base oil and relates to a synthetic method of a chemical industry product. The synthetic method comprises the following steps of: firstly preprocessing n-butyl alcohol, throwing 10-20g of 3A molecular sieve into per kg of n-butyl alcohol, stirring to be uniform, placing for 24 hours, filtering out the molecular sieve, then throwing into the same fresh molecular sieve, and repeating the steps for three times for later use; then sequentially throwing the n-butyl alcohol and a multi-metal catalyst in a reaction kettle, carrying out an initiation reaction, slowly dropwise adding epoxypropane into the reaction kettle, after dropwise adding is finished, discharging when the temperature of the reaction kettle is reduced to 60 DEG C, thus obtaining an intermediate; and finally throwing the intermediate into the reaction kettle, slowly dropwise adding mixture of the epoxypropane and ethylene oxide into the reaction kettle, after dropwise adding is finished, discharging when the temperature of the reaction kettle is reduced to 60 DEG C, and filtering, thus obtaining a finished product. The polyether synthetic base oil prepared by the synthetic method disclosed by the invention has the advantages of high viscosity property, high viscosity index, small variation along with temperature, low flow point and freezing point, stronger lipophilicity, good intermiscibility with various penetrants, better oxidation stability and emulsion performance and certain water-retaining property.

Description

technical field [0001] The present invention relates to a synthesis method, more specifically, to a synthesis method of water-insoluble polyether synthetic base oil. Background technique [0002] The existing water-insoluble polyether synthetic oil uses traditional alkali as a catalyst to synthesize low-molecular-weight diol and triol polyether as an initiator, which is used as an intermediate to synthesize water-insoluble polyether with propylene oxide. Oil. The viscosity characteristic of polyether synthetic oil in the prior art is not high, the viscosity index in the corresponding viscosity product is on the low side, the lipophilicity is not strong enough, the compatibility with mineral oil and various penetrating agents is not good enough, the emulsifying performance is not strong, No water retention. [0003] The present invention uses n-butanol in the monoalcohol, which is formed by two-step polymerization with a certain proportion of propylene oxide and ethylene ox...
