摘要:
A method for producing an aldehyde, which comprises reacting an olefinic compound with carbon monoxide and hydrogen in the presence of a Group VIII metal compound and an organic phosphite compound to produce a corresponding aldehyde, wherein an organic phosphite compound of the formula (I):P(OR.sub.1)(OR.sub.2)(OR.sub.3) (I)wherein each of R.sub.1 and R.sub.2 which may be the same or different, is a 2-naphthyl group which may have a substituent, provided that at least one of R.sub.1 and R.sub.2 is a substituted 2-naphthyl group of the formula (II): ##STR1## wherein R.sub.4 is a C.sub.1-30 organic group, and each of R.sub.5, R.sub.6, R.sub.7, R.sub.8 and R.sub.9 which may be the same or different, is a hydrogen atom or an organic group, and R.sub.3 is 1 a 2-naphthyl group which may have a substituent, 2 a phenyl group which may have a substituent, or 3 an alkyl group which may have a substituent, is used as said organic phosphite compound.

The disinfectant capable of realizing effective sterilization by using a surfactant contains water, from which polyvalent cations are removed and to which a sodium ion is added, and a surfactant. An example of the surfactant is a fatty acid salt. When the disinfectant is applied to an object to be treated, fungi and bacteria adhering thereto are sterilized by the action of the surfactant. The surfactant contained in the disinfectant hardly remains on the object owing to the effect of the water from which polyvalent cations are removed and to which a sodium ion is added, and then is not likely to be a source of nutrient for fungi and bacteria. Accordingly, on the object to which the disinfectant is applied, fungi and bacteria are sterilized and propagation thereof is suppressed, and thus a hygienic state of the object is easily maintained. The disinfectant is particularly effective when it is used for, for example, bathrooms, tabs of washing machines, kitchens, toilets, washstands, drainpipes and daily commodities.

A method for producing an allyl compound having a compositional formula different from that of an allyl starting material compound, which comprises reacting the allyl starting material compound with an oxygen nucleophilic agent in the presence of a catalyst containing at least one transition metal compound containing a transition metal selected from the group consisting of transition metals belonging to Group 8 to Group 10 of the Periodic Table and a multidentate phosphite compound.

摘要:
A process for producing an aldehyde, which comprises a reaction step of producing an aldehyde by reacting an olefinic compound with carbon monoxide and hydrogen in the presence of a rhodium complex catalyst comprising at least rhodium and an organic phosphite in a reaction zone, a separation step of obtaining a catalyst solution containing the rhodium complex catalyst by separating the aldehyde from a reaction solution taken from the reaction zone, and a recycling step of recycling the catalyst solution into the reaction zone, wherein the aldehyde is separated from the reaction solution in such a manner as to make an aldehyde concentration from 0.5 to 99 wt % in the catalyst solution.
摘要:
Hydroformylation process, wherein an olefinic compound is reacted with hydrogen and carbon dioxide in the presence of a Group VIII precious metal complex catalyst containing an organic phosphorus compound as a ligand, the process being characterized by use of trialkyl phosphine, as the organic phosphorus compound, having the total carbon atom number of 27 or more in its alkyl groups.
摘要:
The skin disinfectant, which is able to sterilize skin by the action of a surfactant without damaging skin health conditions, contains water, from which polyvalent cations are removed and to which a sodium ion is added, and a surfactant. The surfactant is, for example, a fatty acid salt. When the skin disinfectant is applied onto skin, fungi and bacteria adhered or parasitic onto skin is sterilized by the action of the surfactant. At this time, the surfactant is not likely to give an irritation to skin due to the action of the water, from which polyvalent cations are removed and to which a sodium ion is added, and thus the skin health conditions tend not to be damaged. Accordingly, the skin disinfectant is useful as a remedy for, for example, a ringworm infectious disease.

The cleaning agent, which is less likely to retain a surfactant on an object to be cleaned and not to restrict applicable objects to be cleaned, contains water from which polyvalent cations are removed and to which a sodium ion is added, and a surfactant. An example of the surfactant is a fatty acid salt. When the cleaning agent is applied to an object to be cleaned, stain adhered on the object is removed from the object by action of the surfactant. The surfactant hardly remains on the object due to the action of the water from which polyvalent cations are removed and to which a sodium ion is added. Accordingly, the cleaning agent can effectively wash a wide variety of objects, such as kitchens, tableware, food, washstands, bathrooms, toilets, vehicles, clothes and body skin, without damaging texture and deteriorating quality.
摘要:
The cleaning fluid, which is easily mass-produced, low priced, and safe and is also free from chemical substances contains water from which polyvalent cations are removed and to which sodium ions are added. When the cleaning fluid is applied to an object to be cleaned, stain adhered onto the object can be removed by action of the water. The object washed with the cleaning fluid is free from remnant of chemical substances, as is often not the case when washed with a cleaning fluid using chemical-substances such as a surfactant, and is therefore safe. Furthermore, since water stain or scale hardly remains on the object washed, new stain is not easily attached. Accordingly, the cleaning fluid is particularly effective when it is used as a cleaning fluid for kitchen sinks, tableware, foods, washstands, bathrooms, toilets, vehicles and clothes.
