Definitions
- the present invention relates to novel, enantiomerically enriched polyethylene glycol esters of R - (+) - 2- (4-chloro-2-methylphenoxy) propionic acid, any mixtures thereof, processes for their preparation and their use as root inhibitors.
- Root growth in building materials leads to undesirable material damage.
- Plastic roots in particular, such as sealing compounds, roofing membranes and asphalt, can be destroyed by plant roots.
- the penetration of roots in the seals of sewers and sewage pipes, in flat roof covers, in the bitumen insulation of pipes, bridges and water structures as well as the ingrowth and ingrowth of roots on light bitumen roads are generally known problems. This can result in leaks, corrosion, damage to buildings, roads and pipes.
- DE-A 4412330 describes processes for the preparation of polyethylene glycol esters of 2- (4-chloro-2-methylphenoxy) propionic acid, which are based on polyethylene glycols with a molecular weight distribution of 170 to 230, the products obtained being said to have improved root-inhibiting properties.
- WO 9506408 describes the use of special esters of 2- (4-chloro-2-methylphenoxy) propionic acid for protecting buildings, building materials and insulating materials against root penetration.
- R represents H or a radical of the formula
- n stands for an integer between 1 and 20
- R * denotes the R configuration of the chiral carbon atom.
- Enantiomerically enriched in the sense of the invention means enantiomerically pure compounds or mixtures of enantiomers of a compound in which one enantiomer is present in an enantiomeric excess, hereinafter also referred to as ee (enantiomeric excess), in comparison to the other enantiomer.
- This enantiomeric excess is preferably 70 to 100% ee, particularly preferably 80% to 100 mol% and very particularly preferably 90 to 100 mol%.
- Enantiomerically enriched in the sense of the invention relates to the configuration of the carbon atom denoted by R * in formulas (I) and (IH).
- the present invention furthermore relates to the use of enantiomerically enriched compounds of the formula (I) or mixtures thereof with one another for protecting industrial materials, in particular buildings, building materials and construction auxiliaries against root ingrowth and growth.
- enantiomerically enriched polyethylene glycol esters of R - (+) - 2- (4-chloro-2-methylphenoxy) propionic acid and the mixtures according to the invention By using the enantiomerically enriched polyethylene glycol esters of R - (+) - 2- (4-chloro-2-methylphenoxy) propionic acid and the mixtures according to the invention, the amounts used to prevent root growth can be significantly reduced. This is particularly favorable for ecological reasons, since only the active enantiomer is used and ineffective compounds are not released into the environment.
- the invention furthermore relates to any mixtures of enantiomerically enriched compounds of the general formula (I) with one another.
- the individual components of the general formula (I) are present in concentrations of up to 80% by weight in these mixtures according to the invention, the sum of the individual components of the formula (I) adding up to 100% by weight.
- inventive higher-enriched polyethylene glycol esters of R - (+) - 2- (4-chloro-2-methylphenoxy) propionic acid of the general formula (I) can be prepared by using polyethylene glycol of the general formula (II)
- n stands for an integer between 1 and 20, preferably for an integer between 2 and 10 and very particularly preferably for an integer between 2 and 8,
- the molar ratio between R - (+) - 2- (4-chloro-2-methylphenoxy) propionic acid of the formula (III) and the polyethylene glycol of the formula (H) is generally between 1: 1.2 and 2.2: 1.
- the molar ratio between R - (+) - 2- (4-chloro-2-methylphenoxy) propionic acid and the polyethylene glycol of the formula (II) is preferably between 1: 1 and 2.1: 1.
- the temperatures of the reaction can be varied within a wide range. Generally they are between 100 and 250 ° C.
- the reaction temperatures are preferably between 130 and 230 ° C, particularly preferably between 150 and 210 ° C.
- the distillation of water of reaction can be supported by applying a vacuum. It is possible to apply a vacuum at the start of the reaction or only in the course of the reaction.
- the vacuum can be reduced to 0.5 mbar, a vacuum of up to 1 mbar is preferably used.
- the mixtures of enantiornerichenriched compounds of the general formula (I) can be obtained either by mixing the enantiornerenriched individual components of the general formula (I) with each other or in the preparation instead of pure polyethylene glycols, mixtures of polyethylene glycols of the general formula (H).
- the polyethylene glycol mixtures used for the synthesis of the mixtures can contain up to 80% by weight of the individual polyethylene glycols of the general formula (II), the sum of the individual components adding up to 100% by weight.
- the enantiomerically enriched polyethylene glycol esters of R - (+) - 2- (4-chloro-2-methylphenoxy) propionic acid of the general formula (I) according to the invention and mixtures of these enantiomerically enriched polyethylene glycol esters of R - (+) - 2- (4-chlorine) -2-methylphenoxy) propionic acid of the formula (I) with one another can be used in particular to protect buildings such as, for example Canals, pipelines, houses, roofs, streets, bridges and hydraulic structures as well as building materials and construction aids such as Cement, plastic films, roofing membranes and building material preparations such as Coatings, sealing and insulating compounds against ingrowth and through-growth of roots can be used.
- the compounds of the formula (I) according to the invention or mixtures thereof can generally be applied directly to the industrial materials to be protected or mixed with them.
- Buildings are treated directly with the compounds of formula (I) according to the invention or their mixtures, or they can be treated with building material preparations e.g. on the basis of bitumen or tar pitches containing one or more compounds of the formula (I) according to the invention.
- the building materials and building aids can e.g. are mixed with the compounds of formula (I) according to the invention or their mixtures.
- the building material preparations can be prepared by adding or mixing a commercially available building material preparation, for example based on bitumen or tar pitch, or a paint or a sealing or insulating compound, with one or more compounds of the formula (I).
- the content of enantiomerically enriched active ingredient of the formula (I) in the building materials, building aids and building material preparations is in general from 0.01 to 20% by weight, preferably 0.01 to 5% by weight, particularly preferably 0.1 to 2% by weight based on the respective preparation or the respective building material.
