Description

IMPROVEMENTS IN OR RELATING TO ORGANIC COMPOUNDS
This invention relates to compositions, particularly for agrochemical use, comprising certain lactamides and biologically active compounds, and to methods of making and using such compositions. In particular the present invention relates to such compositions when formulated as, or comprised by, an emulsion concentrate (EC).
An agrochemical (fungicidal) composition comprising dimethyl lactamide and triforine is disclosed in DE 41 12 873 Al .
Certain lactamides are disclosed in Ratchford, W. P. and Fisher, C. H., Journal of Organic Chemistry, 1950, 15, 317-325; Ratchford, W. P., Journal of Organic Chemistry, 1950, 15, 326-332; Fein, MX. and Filachione, E.M., Journal of the American Chemical Society. 1953, 75, 2097-2099; and US 4,143,159.
Nowadays, the Formulation Chemist is required to address a number of environmental criteria when developing new formulations. Ideally, a suitable solvent will display many or all of the following properties: an excellent dissolving power for pesticides or other biologically active compounds; made from plant or animal renewable resources; low skin irritation; an ability to reduce the skin irritation associated with aggressive formulation components, such as sodium lauryl sulphate; low ecotoxicity, for example to daphnia; low volatile organic content; and a high flash point. The compositions of the present invention comprise a solvent which displays all or many of these attractive properties.
However, not all solvents are equal with respect to their capacity to dissolve biologically active compounds - the nature of the compound and its interaction with the solvent is substantially decisive. It has surprisingly been found that a particular class of solvent is surprisingly effective in dissolving a particular class of biologically active compound. According to the present invention there is provided a composition comprising a compound of formula I
CH3CH(OH)C(=O)NR1R2 (I)
where R1 and R2 are each independently hydrogen; or C1-6 alkyl, C2-6 alkenyl or C3-6 cycloalkyl, each of which is optionally substituted by up to three substituents independently selected from phenyl, hydroxy, C1-5 alkoxy, morpholinyl and NR3R4 where R3 and R4 are each independently C1-3 alkyl; or phenyl optionally substituted by up to three substituents independently selected from Ci-3 alkyl; or R1 and R2 together with the nitrogen atom to which they are attached form a morpholinyl, pyrrolidinyl, piperidinyl or azepanyl ring, each of which is optionally substituted by up to three substituents independently selected from Ci-3 alkyl;
and at least one agrochemical selected from the group consisting of Trinexepac ethyl, Mandipropamid, Abamectin and Emamectin, with the proviso that the agrochemical is not abamectin or emamectin when the solvent is N-(B-hydroxyethyl)- lactamide.
The structure of Abamectin is shown in Figure 1.

Alkyl groups and moieties are straight or branched chains. Examples are methyl, ethyl, isO-propyl, ra-propyl, n-butyl, sec-butyl, tert-batyl, H-amyl and iso-amyl [3-methylbutyl]. Alkenyl groups and moieties may be in the form of straight or branched chains and, where appropriate, may be of either the (E)- or ©-configuration. Examples are vinyl and allyl.

In one aspect of the composition, in the compound of formula I R1 and R2 are each independently hydrogen; or C1-6 alkyl which is optionally substituted by up to three substituents independently selected from phenyl, hydroxy, C1-5 alkoxy, morpholinyl and NR3R4 where R3 and R4 are each independently C1-3 alkyl; or R1 and R2 together with the nitrogen atom to which they are attached form a morpholinyl ring which is optionally substituted by up to three substituents independently selected from Cj-3 alkyl.

In an even further suitable aspect, R1 is methyl and R2 is methyl, propyl or butyl; or R1 and R2 together with the nitrogen atom to which they are attached form a morpholinyl ring. R3 may be methyl, as may R4 . For each optional substituent, it is preferred that it is a methyl group. Suitably alkyl groups are branched; most suitably with methyl groups.

The composition may further comprise a solvent selected from the group consisting of aliphatic solvents; straight or branched chain paraffins; cyclic hydrocarbons; aromatic solvents; phosphorus containing solvents; sulphur containing solvents; nitrogen containing solvents; aliphatic mono, di or triesters; aromatic mono and di esters; cyclic esters; cyclic, aliphatic and aromatic ketones; alkyl cyclohexanones, dialkyl ketones, acetoacetates, benzyl ketones,; acetophenone; alcohols; cycloalcohols; glycols; glycol ethers and their polymers; propylene glycols; glycol ether acetates; aromatic alcohols; carbonates; ethers and halogenated solvents.
Particularly preferred further solvents are white oil; decalin; mono, di or tri alkylated benzenes; Solvesso 100 or 200ND (t); triethyl phosphate;tributyl phosphate; tri- 2-ethylhexylphosphate;methyl oleate;linoleic acid;linolenic acid;oleic acid;dimethyl decanoamide; tetramethyl sulphone; dimethyl sulphoxide;alkyl ureas; alkanolamines; morpholines; amides; alkyl alkanoates, lactates and acetoacetates; fumarates; succinates; adipates; maleates; glycerol and citric acid esters;alkyl benzoates; benzyl alkanoates; alkyl salicylates; phthalates and dibenzoates; gamma butyrolactone; caprolactone; terpene fenchone; cyclohexanone; alkyl cyclohexanones; 2-ethylhexanol and other alkyl alcohols; cyclohexanol; tetrahydrofurfuryl alcohol; ethylene and propylene glycol and their polymers; dipropylene glycol; monomethyl or monobutyl ether; dipropylene glycol diacetate or other glycol ether acetates, or tripropylene glycol monobutyl ether; benzyl alcohol; propylene or butylene carbonate; dimethyl isosorbide; alkoxyalkanols; diphenyl ether; chlorobenzene and the chloroalkanes.

The surfactant, may be non-ionic (for example a nonylphenol ethoxylate or an alcohol ethoxylate), anionic (for example an alkyl sulphate, such as sodium lauryl sulphate, or a sulphonate, such as calcium dodecylbenzene sulphonate) or cationic (for example a tertiary amine).
The compound of formula 1 may be present in the composition in an amount of from 0.1 to 99 % by weight of the composition and the agrochemical, may be present in an amount of 0.1 to 75 %, likewise by weight.
In a preferred embodiment of the composition, the compound of formula 1 may be present in an amount of from 0.1 to 99 % by weight of the composition, the agrochemical may be present in an amount of 0.1 to 75 %, by weight and the solvent may be present in an amount of 0.1 to 90 %, likewise by weight.
The ratio of compound of formula 1 to agrochemical to solvent maybe varied according to needs, a ratio of 1 : 1 : 1 or near to these limits is likely to be valuable for many of the desired formulations however the limits on each component could be as low as 0.01 : 1 for the ratio of any two parts of the formulation.
The lactamide component of the present compositions may be prepared by reacting a compound of formula (III) [CH3CH(OH)C(=O)OR5 (III)] where OR5 is a leaving group, with a compound of formula (II) [HNR1R2 (II)] where R1 and R2 are as defined above. R5 may be C1-4 alkyl. This process produces HOR5 as a by-product; a cleaner reaction avoids this by-product: the lactamide component of the composition of the present invention may also be prepared by reacting lactide [3,6-dimethyl-[l,4]- dioxane-2,5-dione] with a compound of formula (II) [HNR1R2 (II)] where R1 and R2 are as defined above. Schematically, such a reaction is shown below: A,A + 2 HNR1R2 (II) 2 CH3CH(OH)C(=O)NR1R2 (I)
The synthesis is not limited to the above reaction scheme; it illustrates how lactide [3,6-dimethyl-[l,4]-dioxane-2,5-dione] may be converted to a lactamide by reacting lactide with an amine [suitably a primary or secondary amine] which may be carried out under "solvent-free" conditions as the skilled artisan will appreciate.
In a particularly preferred embodiment of the present inventive composition, the ratio of compound of formula 1 to agrochemical to solvent is 1 : 1 : 1 or 2: 1 : 1 or 2:1 :2 or 3:1:1 or 3 : 1 :2 or 4.5 : 1 :4.5 or 6: 1 :3 and in a still more preferred embodiment, the compound of formula 1 is dimethyl lactamide (DML).
The skilled man will recognise that the present compositions may be formulated as emulsion concentrates, emulsions in water or oil, microencapsulated formulations, aerosol sprays or fogging formulations; and these may be further formulated into granular materials or powders, for example for dry application or as water-dispersible formulations. The solutions so formed may also be used directly on soil or plants or in other, non-agrochemical, applications.
The particularly preferred formulated form of the composition is as an emulsion concentrate (EC).
The present inventive compositions have a low unwanted toxicity and excellent environmental profile meaning that they are particularly useful in applications where the minimisation of pollution is desired. Examples of such applications include paper making, water treatment, forestry applications, public health treatments, use in municipal pools and other water courses, in applications near rivers, lakes, reservoirs or seas and in applications where release to the atmosphere has to be minimised or controlled and where damage to the atmosphere is not desirable. Examples include use of fungicide containing compositions according to the present invention in exterior and interior paints, coatings, varnishes, waxes or other protectant layers or opacifϊers, colourants or screens; in dyeing, pigmentation or the use of inks; in cleaning products designed for the home, garden or industrial applications; and in soap or detergent applications for industrial, home or environmental usage. The compositions of the present invention may also be used in shampoos, and in househould detergents and household cleaners (for example surface cleaners), in which the active ingredient may be a fungicide (possibly azoxystrobin) in the case of shampoo or a bacteriocide in the case of the detergents and cleaners.
The present invention also provides a method of making the inventive composition disclosed above by admixing a compound of formula 1 as indicated above with an agrochemical.
The present invention also provides a method of controlling an agricultural pest comprising application to the pest, to a locus comprising it or to a surface on which it is capable of being present, of a pesticidally effective amount of a composition according to the invention.
The invention still further provides the use of the present inventive composition to control a plant pest.
The compositions of the present invention are particularly valuable in formulations where contact with either human or animal skin or eyes is required or may occur by accident. Applications such as the use of shampoo or body cleaning fluids (such as shower gels, hand or body wipes and medical wipes) may benefit from the safe nature of the lactamide solvent present in the composition, which may form part of a cleaning formulation and which may also reduce the irritancy of some of the other ingredients, such as surfactants. In a similar fashion the irritation to skin or eyes caused by the direct application of pharmaceutical or veterinary compositions to them may be reduced relative to the like application of prior art compositions containing the same pharmaceutically active ingredients.
