Description

With 1,1-two chloro-1-fluoroethanes are the compsition for dry washing of base
The present invention relates to a kind of basically by 1, the compsition for dry washing that 1-two chloro-1-fluoroethanes and at least a tensio-active agent that is selected from anion surfactant and nonionogenic tenside are formed.
Dry-cleaning is meant by a kind of solvent and handles the clothes of making dirty, in general, the fabric that should in water, clean not, for example silk, hair, leather, microgroove fabric etc. must be dry-cleaned, and the clothes of other class also can strengthen washing effect with dry-cleaning.Typical spot on these clothes comprises water-soluble spot, food stains for example, and this spot organic solvent is difficult for removing.Find that if compsition for dry washing contains tensio-active agent, then except the solvent soluble spot, the also available dry-cleaning method of other water-soluble spot is removed.
Typical dry-cleaning equipment comprises a washer that has circulating line and pump, and solvent is through washer, then by the strainer washer that comes out to return again.Strainer has been removed dirt, has purified solvent, makes it to utilize again.In a batch dry cleaning system, for example the clothing of being made dirty rolls in solvent, and solvent is filtered then, and recycling.
Dry cleaning solvent commonly used is the about 121 ℃ tetrachloroethylene of boiling point, because it is deleterious, is not suitable for as dry cleaning solvent.
Chloro-containing fluorocarbon solvent, for example Refrigerant R 113 owing to its effective, nontoxic, non-inflammability, has obtained widespread use in recent years in the purposes of all kinds of SOLVENTS that comprises dry-cleaning.A kind of isomer of Refrigerant R 113 is 1,1,2-three fluoro-1,2, and 2-trifluoromethane (being called CFC-113 in the art), about 47 ℃ of the boiling point of CFC-113 has found that it has gratifying dissolving power to grease, oils wax etc.
Although chlorine is known for the dissolving power of promoter action compound; but suspected that complete halogenated chlorofluorocarbon and hydrogeneous chlorocarbon have infringement and cause environmental protection problem the ozone layer of the earth; so; those skilled in the art person is seeking the solubility property that had both had CFC-113 always, can not produce the new compound of harm to environment again.From point of view of environment protection, people are interested in the hydrochlorofluorocarsolvent, because it is considered to than present used complete halogenated chlorofluorocarbon safety.Mathematical model is verified, hydrochlorofluorocarsolvent, for example 1,1-two chloro-1-fluoroethanes (being known as HCFC-141b in this field) do not have disadvantageous effect to the atmospheric chemistry composition, compare with complete halogenated chlorofluorocarbon, the former is negligible to the influence of ozone-depleting and Global Greenhouse Effect.
In all dry-cleaning processes, require to remove oil stain and solid dirt, remove water-soluble dirt, avoid the redeposited of dirt, and the contraction of avoiding clothing, at the same time, also require to have a kind of compsition for dry washing that the atmospheric chemistry composition is not had disadvantageous effect.
The Kokai patent Publication 139 that on June 1st, 1989 published, 861 have disclosed a kind of dry cleaning composition, it contains the Azeotrope compositions of 99% weight, wherein 67% weight is 1,1-two chloro-2,2, the 2-Halothane, 33% weight is 1, the Sodium dodecylbenzene sulfonate of 1-two chloro-1-fluoroethanes and 1% weight.Unfortunately, 1,1-two chloro-2,2,2-Halothane and 1,1-two chloro-1-fluoroethane Azeotrope compositions and the polymer materials for example consistency of button are not still complied with one's wishes.
A kind of compsition for dry washing is removing stain, stop stain redeposited and when preventing that clothing from shrinking, can not have a negative impact to the atmospheric chemistry composition, solution to this technical need provides a kind of compsition for dry washing, it contains basically by 1, and 1-two chloro-1-fluoroethanes and at least a tensio-active agent that is selected from cats product and nonionogenic tenside are formed.Preferable is basically by 1 of the about 99.98 weight % of about 96-, and at least a tensio-active agent that is selected from anion surfactant and nonionogenic tenside of 1-two chloro-1-fluoroethanes and the about 0.04 weight % of about 0.02-is formed.
We have found that a kind of compsition for dry washing, it not only has than CFC-113 and the good washing of tetrachloroethylene renders a service, and the deposition again of stain on the clothes is reduced.This novel compsition for dry washing is basically by 1, and 1-two chloro-1-fluoroethanes and at least a tensio-active agent that is selected from anion surfactant and nonionogenic tenside are formed.
Preferably, this novel composition is basically by 1 of significant quantity, and 1-two chloro-1-fluoroethanes and at least a tensio-active agent that is selected from anion surfactant and nonionogenic tenside are formed.Be meant and the amount of combined each component of other each component at this used term " significant quantity ", make this dry-cleaning compound of formation have gratifying detergency ability and minimum deposition properties again.
This compsition for dry washing is owing to following reason is favourable: each component is negligible to the influence of ozone depletion, said composition also has the better clean effect than CFC-113, than tetrachloroethylene littler toxicity and better material consistency, the deposition again of dirt is also less on clothes.
Preferable is the mixture of using negatively charged ion and nonionogenic tenside.
