Patent GB-2025950-A (GB)
Title: The Preparation of Esters of Oxalic Acid
IPC: C07B61/00
Filed: 1979-06-25
Abstract: Alkyl oxalates in which the alkyl groups have 1-10 carbon atoms are made by reacting the corresponding alkyl nitrite with carbon monoxide in the presence of a noble metal catalyst (palladium, rhodium, iridium, platinum or gold) at an elevated temperature, suitably 50 DEG -500 DEG C, preferably 150-350 DEG C. An iron or copper co- catalyst may be used; the latter may serve as carrier for the noble metal or the two may if desired be on a common support, and either or both may be used in salt form or as the metal. The reaction proceeds conveniently in the gas phase, suitably under atmospheric pressure of higher. Significant advantages include the absence of by-product water, the possibility of converting by-product nitric oxide to alkyl nitrite for re-use, the viability of synthesis gas as carbon monoxide source and, related to this, the absence of oxygen as reactant. The ester can, of course, be hydrolised to oxalic acid when this is required as end product.

Title: Enhancement of the sensitivity of bioluminescent and chemiluminescent assays with enzymatic cycling
IPC: C12Q1/48
Filed: 1980-07-22
Abstract: Bioluminescent and chemiluminescent assays coupled with enzymatic cycling systems greatly increase the versatility and sensitivity of substrate and enzyme assays based on enzymatic cycling principle. Besides the normal pyridine nucleotide cycling system it is possible to use the adenine nucleotide system when the produced substrates are measured by the bioluminescent assay of ATP. Utilizing the bioluminescent assays of NADH, NADPH or ATP, or the chemiluminescent assay of H2O2 or O2 it is possible to measure more substrates produced in the enzymatic cycling systems than has been possible by spectrophotometry or fluorometry. The sensitivity of the measurement with the luminescent assay systems are 2 to 3 orders of magnitude higher than with fluorometry.

Title: A method of treating seed for the control of disease and liquid seed dressing compositions
IPC: A01N25/02
Filed: 1980-09-30
Abstract: A method of treating seed for the control of disease comprises applying to the seed 150 to 250 g of triforine, per 100 kg of seed, the triforine being present in a liquid seed dressing composition, the solvent medium of which consists of at least two solvents selected from dimethylformamide, diethylformamide, N-methylpyrrolidone and dimethylsulfoxide with the proviso that where the medium consists of dimethylformamide and N-methylpyrrolidone the weight ratio of dimethyl formamide to N-methylpyrrolidone is 7:3 to 1:9. In addition to maintaining an at least equivalent activity against genuine mildew in spring barley this method renders it possible to obtain a significant increase in crops and to control diseases other than genuine mildew by applying to the seed a reduced quantity of triforine, than hitherto conventional. Liquid seed dressing compositions comprising as active ingredient from 200 to 290 g of triforine in the aforementioned mixture of solvents are also described and claimed.
