Abstract

This invention relates to a formulation comprising a compound of formula (I) where R1 is hydrogen, methyl, ethyl, propyl or butyl; R2 is methyl or ethyl; R3 is hydrogen, methyl or ethyl; and n is 1, 2 or 3; to the use of a compound of formula (I) as a solvent; and to certain novel compounds of formula (I).

Description

FORMULATIONS
This invention relates to the use of certain alkylene glycol benzoate compounds as solvents, especially in formulations, particularly in agrochemical formulations and in cnvironmcntally fricndly formulations; and to certain novel compounds. The solvents of the présent invention are found to be particularly effective when solubilising pesticides of the families strobilurins, triazoles and succinate dehydrogenase inhibitors (SDIII) (particularly pyrazoles; suitably pyrazam chemistry).
Nowadays, the Formulation Chemist is required to address a number of environmental critcria when developing new formulations. Ideally, a suitable solvent will display many or ail of the following properties: an excellent dissolving power for pesticides or other organic molécules; made from plant or animal renewable resources; low skin irritation; low ecotoxicity, for example to daphnia; low volatile organic content; and a high flash point. The compounds of the présent invention each display ail or many of these properties, in particular an excellent dissolving power; the compounds may be used effectivcly as solvents.
Accordingly, the présent invention provides a formulation comprising a compound of formula (I)
R3 (I where R1 is hydrogen, methyl, ethyl, propyl or butyl; R2 is methyl or ethyl; R3 is hydrogen, methyl or ethyl; and n is 1, 2 or 3.
Propyl and butyl groups are straight or branched chains. Examples are «o-propyl, n-propyl, n-butyl, sec-butyl and tert-butyl.
Suitably R1 is H.
Suitably R2 is methyl.
Suitably R3 is H.
Suitably n is 1.
Suitably the invention provides the use of a compound of formula (1) in an agrochemical formulation.
The compounds of the présent invention may be used as solvents.
Many of the compounds disclosed by the présent invention are novel.
-2Therefore in a further aspect, the présent invention provides a compound of formula (I) as defined above; provided that the compound is not 2-hydroxypropyl benzoate,
2-hydroxy-1 -methylethyl benzoate, l ,2 butanediol-2-benzoate, l,2 butancdiol-l-benzoate or l-propanol-2(2-hydroxypropoxy)-l-benzoate.
Table l provides structures and certain spectroscopic data for suitable compounds of formula (I):

The compounds of the présent invention are easy to prépare; for instance, a glycol ether îs rcactcd with an aromatic compound with a suitable leaving group, for example benzoyl chloride.
The compounds of the invention may bc used in a variety of end use applications (including agrochemical formulations), particularly as solvents. These solvents may be used with a wide variety of materials, including herbicides, fongicides, acaricides, nematicides and insecticides [and also plant growth rcgulators].
The présent invention encompasses all isomers, or mixtures of isomers, of compounds of formula (I) and also encompasses mixtures of two or more different compounds of formula (I).
The compounds of the invention may bc used to formulate solutions of a variety of materials, including agrochemicals, which may be formulated as émulsion or dispersion concentrâtes, émulsions in water or oil, microcncapsulated formulations, aérosol sprays or fogging formulations; and these may be forther formulated into granular materials or powders, for example for dry application or as water-dispersîblc formulations. The solutions so formed may also bc used directly on soil or plants or in other non-agrochemical applications.
Examples of such applications include paper makîng, water treatment, forestry applications, public health treatments, use in municipal pools and other water courses, in applications ncar rivers, lakes, réservoirs or seas and in applications where release to the
-3atmosphère has to be minimîsed or controlled and where damage to the atmosphère îs not désirable. Examples include use in exterior and interior paints, coatings, vamishes, waxes or other protectant layers or opacifiers, colourants or scrcens; in dyeîng, pigmentation or the use of inks; în clcaning products designed for the home, garden or industrial applications; and in 5 soap or detergent applications for industrial, home or cnvironmental usage. The compounds of the présent invention may also bc used in shampoos, houschold detergency and in household cleaners [for example oven cleaners and surface cleaners].
The compounds of the présent invention hâve exceptional dissolving power for a wide variety of agrochcmîcals, pharmaceuticals and other commercially valuable compounds, plus 10 the dissolving power also extends to dissolution of dirt, grease or waxes.
The invention is illustrated by the following Examples in which:
g = grammes °C = degrees centigrade
Unless otherwise stated, each concentration is expressed as pcrcentage by weight.
The solvents of the présent invention arc particularly effective when solubilîsing pesticides bclonging to the familles: strobilurins, triazoles and succinate dehydrogenase inhibitors (SDHI) (particularly pyrazoles; suitably pyrazam chemistry). This fact is demonstrated in the cxamples where it îs shown that the solubility of the pesticides azoxystrobin, difenoconazole and isopyrazam arc higher in the solvent propylene glycol benzoate than in a sériés of commonly used solvents. Surprisingly the solubility of cyprodinil, chlorothalonil and bicyclopyronc in propylene glycol benzoate is lower than in the same séries of common solvents. Solubilities arc quoted as pcrcentage w/w at 20°C.
EXAMPLE 1
This Example illustrâtes the high solubility of each of a number of agrochcmical active ingrédients in solvents ofthe présent invention [compounds I and 2 ofTable 1].
A glass vial was approximately one eîghth fiillcd with an active ingrédient [AI] and then solvent [in this example, propylene glycol benzoate or butylène glycol benzoate] was added until the vial was approximately one third fùll. The résultant sample was mixed with a Whirlimixer™ and was then stored at 25°C. The sample was chcckcd every few days; if there was no solid active ingrédient présent then additionaî active ingrédient was added; if there was no liquid remaining then additionaî solvent was added. This procedure was repeated until the sample had equilibrated for 4 weeks following the final addition of either active ingrédient °( or solvent. The supematent liquid layer was then analysed by gas chromotography for active ingrédient concentration; the results are given in Table 2:

EXAMPLE 2
This Example shows that the solvents ofthe présent invention are particularly effective when solubilisîng pesticides bclonging to the familles: strobilurîns, triazolcs and succinate dehydrogenase inhibitors (SDHI) (particularly pyrazoles; suitably pyrazam chemistry). Tables 3a and 3b show the solubility of the pesticides azoxystrobin, dîfenoconazole, isopyrazam, cyprodinil, chlorothalonil and bicyclopyrone in the solvent propylc glycol benzoate [compound 1 of Table 1], For comparison the solubilities in a sériés of commonly used solvents arc also tabulated. The data show that in most cases the propylene glycol benzoate îs a better solvent for the first three pesticides (respectively a triazole, an SDHI and a strobilurin,) than are the other common solvents. Solubilities are quoted as percentage w/w at 20C.
