The present invention relates to novel herbicidal and plant growth-inhibiting 2-substituted 5-phenoxyphenylphosphonic acid derivatives of the formula ##STR1## wherein each of R.sub.1 and R.sub.2 independently is hydroxyl, lower alkoxy, lower alkylthio, alkylamino, dialkylamino, chlorine, benzyloxy or benzylthio, X is halogen or a --CF.sub.3, --NO.sub.2, --CN, --CONH.sub.2 or --CSNH.sub.2 group, n is 0 to 3, and Y is --OH, halogen, NO.sub.2, --CN, NH.sub.2, --NHCO--R, --NHCOOR or --NH--SO.sub.2 --R, wherein R is an unsubstituted or halogenated lower alkyl radical. Preferred compounds are 2-nitro-5-(2'-chloro-4'-trifluoromethylphenoxy)-phenylphosphonic acid and the lower dialkyl esters thereof. The invention also relates to the production of the novel phosphonic acid derivatives, starting from a 3,4-dinitrodiphenyl ether and reacting it with a trialkylphosphite as first step. The invention further relates to herbicidal and plant growth-regulating compositions which contain one of the novel compounds as active component, and also to the use of these compounds and compositions for controlling weeds (also selectively), for inhibiting plant growth and desiccating parts of plants above the soil, as well as for totally destroying existing plant growth.
摘要:
Phosphonic acid halides are prepared by reacting a dialkylphosponate with thionyl chloride or thionyl bromide in the presence of a nitrogen compound from the group comprising N,N-disubstituted formamides, tertiary amines and N,N-disubstituted phosphoric acid triamides. Phosphonic acid dihalides as well as phosphonic acid alkylester monohalides can be prepared by the new process.

Fuel is conveyed by at least one high-pressure pump from a low-pressure region into a high-pressure region including a pressure-accumulator line consisting of at least two separate accumulator units connected to one another by means of feed lines, and to fuel injectors for the cylinders. The accumulator units each have an accumulator volume for serving at least two cylinders, and accumulator covers provided on both end faces. All the functional units are integrated into these accumulator covers in terms of fuel delivery and transfer, and at least one separate pump accumulator is arranged in the high-pressure region between the high-pressure pump and the assembled pressure-accumulator line. The pump accumulator is connected to at least one accumulator cover of an accumulator unit of the pressure-accumulator line for fuel conveyance and is capable of being acted upon by at least one high-pressure pump.
