Description
Technical field
The invention belongs to technical field of fine, particularly a kind of preparation method of stable higher aliphatic alcohols degasser.
Background technology
Bubble and foam, often along with life and the production of people, need to utilize it, as flotation, fire extinguishing, dedusting, washing, manufacture foamed ceramics and plastics etc. sometimes; But sometimes must eliminate again, because it brings very large harm to industrial production, its harm is main as follows:
(1) production capacity is reduced.As various biofermentation (Beer Brewage, alcohol manufacture, pharmaceutically each large antibiotic production ...) in the equipment such as fermentation tank reactor cooker, in order to prevent the appearance of foam, cause overflowing loss, batch charging coefficient will be had a greatly reduced quality, and does not sometimes reach 30%.
(2) due to the generation of foam, and cause reaction mass to overflow reactor, cause the waste of raw material.
(3) because the collision between raw material is insufficient, reaction time is extended.
(4) decline of product quality is caused.As in the dyeing in textile industry, stamp and water paint technical process, due to the delay of bubble, cause spot on finished fabric, fault; The foam of pulp slurry is except working the mischief to environmental sanitation, workers ' health, and finished paper also there will be many holes, causes product quality degradation.
(5) cause operation passive, the generation of foam makes production normally to carry out.Due to the existence of foam, the measurement of interference liquid level meter is accurate, and cause and measure error, cause fluid density generation larger fluctuation, induce reaction still absorption tower destilling tower liquid level virtual height, causes operation disequilibrium, even have an accident.
(6) contaminated environment, cause accident: because foam overflows, will inevitably pollute production environment and surrounding environment thereof, what have even causes a serious accident.Therefore people try every possible means to prepare various types of froth breaking degasser and solve bubble-related issues in these production processes, wherein higher aliphatic alcohols froth breaking degasser is widely used in papermaking with the cost that the performance of its excellence is cheap, water treatment, fermentation, coating, printing and dyeing, food, starch processing is degassed with froth breaking in pharmacy etc. aqueous systems, and the degassed effect of its froth breaking obtains the very big accreditation of each commercial Application personage.But the fusing point of the main component of such froth breaking degasser is all higher, under room temperature state, major part is all in solid-state, be easy in the solution after emulsification assemble condensation, namely emulsion itself is stable not, along with prolongation and the variations in temperature in storage time, finally probably become body of paste and even condense into a monoblock and the not any mobility of tool thus have influence on pumping and the result of use of product; Also there is serious lamination with the prolongation in storage time and variations in temperature thus have influence on the result of use of product in some product.Although researchers have done a large amount of work and applied for the patent of invention of many this respects in this respect, but these technology do not obtain real large-scale application, though Simultaneous Stabilization increases thoroughly do not resolve this difficult problem due to the aspect such as cost or raw material sources factor.As patent CN1781574A describes the way that the polyethers emulsifying agent using isomery primary alconol and oxirane to be formed carrys out stabile fat alcohol emulsion, US5744066 describes and uses isooctyl phenol polyethoxylate and hydrosulphate to prepare the method for aliphatic alcohols defoamer as emulsifying agent, US5807502 introduces with C6 ~ 18 1, the product of 2-glycol and ethyleneoxide addition prepares the method for fatty alcohol defoamer as emulsifying agent, CN101530759A describes and uses special fatty alcohol ethylene oxide propylene oxide copolyether and anion surfactant coupling, the method simultaneously adopting synthetic fatty alcohol to mix with natural fatty alcohol prepares the method stablizing cheap fatty alcohol defoamer, CN101690857A describes and adopts special fatty alcohol ethylene oxide propylene oxide copolyether and alkyl glucoside surfactant coupling to prepare the method for natural high class fatty alcohol defoamer, CN101733039A describes and adopts special fatty alcohol ethylene oxide propylene oxide copolyether and alkyl glucoside surfactant coupling to prepare the method for synthesizing higher aliphatic defoamer, CN103572652A describes and uses a kind of water-soluble polypropylene of special construction acid high-carbon alcohol ester to decide body raw material to prepare the method for fatty alcohol defoamer, CN101718055A describes the method using polysaccharide compound and water-soluble phenylethene-maleic amide acid copolymer and non-cationic surfactant synergy to form stable fatty alcohol defoamer, CN103298999A describes the method using the amphipathic copolymer surfactants of special construction and anion surfactant to share to prepare fatty alcohol defoamer, but the long-time stable sex chromosome mosaicism of all thorough workout cost and raising emulsion.
Therefore, a kind of preparation method of stable higher aliphatic alcohols degasser is badly in need of to overcome above-mentioned defect.

Stability and defoamer performance test
By product prepared in embodiment and comparative example, adopt the digital rotation viscometer of NDJ-5, test under 2#, 6rmp/min condition, test result is as shown in table 1 below:
Table 1 aliphatic alcohols froth breaking degasser is viscosity B coefficent data under different temperatures different memory time
Can be drawn by table 1, in the emulsion adopting method of the present invention to prepare 6 months, at each temperature, viscosity B coefficent is very little, and the test that product can bear low temperature and thaw, products obtained therefrom is very stable.These storing temperature conditions meet the temperature changing regularity of China's the South and the North completely, and the good fluidity of product is conducive to pumping thus is conducive to applying of product, has extraordinary market application foreground.
The mensuration of antifoaming performance: think interior through 50mm, volume 2000ml and be with in graduated cylindrical glass container and add 800ml corrugated paper copy paper plain boiled water, plain boiled water is heated to 45 DEG C, add rapidly this plain boiled water and the bubbling that circulates immediately, after foam being mentioned reach 400ml, add the froth breaking degasser in quantitative freshly prepd embodiment and comparative example, record the situation of change of different time points foam volume simultaneously, specifically as shown in table 2:
Antifoaming performance data at 45 DEG C, table 2
Illustrate: better at the froth breaking degasifying effect putting the less explanation product of foam volume at the same time, the froth breaking degasser adopting the present invention to obtain as shown in Table 2 shows excellent disappearing and presses down bubble effect in corrugated paper system plain boiled water.The cooperative effect of adding Guerbet alcohol and biological polyoses alcohol and controlling stick not only increases the stability of product and improves the froth breaking degasifying effect of product, is the method for the stable higher aliphatic alcohols degasser of a kind of very effective preparation.
The present invention is the fatty alcohol froth breaking degasser product that under a low temperature, (45 DEG C) use.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
