The present invention concerns a process for separation of a monomer including at least one double bond, hereafter referred to as “monomer,” in particular (meth)acrylic acid, from a composition Z including this monomer and at least one impurity different to the monomer, including the steps of bringing into contact of the composition Z with an additive by forming a separation phase. The additive has a melting point of at most about 150° C. and a vapour pressure at a temperature of 20° C. of at most about 1 mbar. The monomer is then separated from the separation phase. A device for producing a monomer, the use of additives in the separation of a monomer from a monomer-comprising composition, the monomer obtainable by the process according to the invention, chemical products comprising the monomer as well as the use of the monomer in or for production of chemical products.

The invention belongs to the field of daily chemical products, particularly relates to bacteriostatic foot powder and a preparation method thereof, and provides bacteriostatic foot powder. The bacteriostatic foot powder comprises the following components in percentages by weight: alkannin 1-3%, cinnaldehydrum 2-4%, berberine 1-5%, patchouli alcohol 2-4%, menthol 1-2%, alkyl glycoside 2-6%, tea saponin 0.5-1.5%, dipotassium glycyrrhizinate 1-3%, a deodorant 2-10%, ethanol 5-25% and corn flour 36.5-82.5%. The bacteriostatic foot powder not only can effectively improve foot hyperhidrosis and prevent and treat foot odour, but also can inhibit bacteria, diminish inflammation and resist allergy, and effectively treats tinea pedis. Meanwhile, the provided bacteriostatic foot powder is gentle in property, and is safe and non-irritant.

The invention belongs to the field of chemical product preparation, and in particular, relates to a multi-functional pet shower lotion and a preparation method thereof. The multi-functional pet showerlotion is prepared from the following raw materials by mass: 5-20 parts of Chinese honeylocust fruit raw liquid, 2-4 parts of glycerin, 70-85 parts of rose pure dew, 1-2 parts of radix angelicae dahuricae, 2-3 parts of sweet apricot kernel oil and 10-15 parts of PHMB. The multi-functional pet shower lotion can moisturize the skin while cleaning pet fur, makes the fur glossy, smooth and easy to comb, dispels the body odor of the pet fur, inhibits breeding of bacteria, and removes parasites on the pet body surface while bathing.

The invention disclosesorganic fertilizer for fruits and vegetables. The organic fertilizer is characterized by being prepared from raw materials in parts by weight as follows: 100-150 parts of livestock manure, 50-100 parts of rice straw, 50-100 parts of leaves, 30-60 parts of tea residues, 10-20 parts of organic fertilizerzymophyte, 20-30 parts of bran, 30-50 parts of plant ash, 20-50 parts of rotten vegetable leaves, 10-20 parts ofartemisia vulgaris, 10-20 parts of glycyrrhizauralensis, 200-300 parts of washing water of rice and 100-200 parts of soybean water, wherein soybeans account for 10%-20% of the soybean water. Theorganic fertilizer for fruits and vegetables contains no chemical products and is environment-friendly, the plant ash not only contains a large quantity of mineral substances, but also has functions of sterilization and disinfection, the glycyrrhizauralensis, the artemisia vulgaris and the tea residues have certain pharmacological function and can improve resistance of plants, the organicfertilizer has comprehensive nutrition, and plant growing effect is good.

The invention discloses a trimethyl phosphate preparation method, which comprises following steps: carrying out a mixing reaction on methanol and phosphorus oxychloride, removing hydrogen chloride gas under a negative pressure during the reaction process, carrying out high-negative-pressure low-temperature distillation on the remaining methanol after the reaction, and carrying out rectification to obtain trimethyl phosphate. Compared with the prior art, the preparation method of trimethyl phosphate has the advantages that no wastewater is generated, the wastewater treatment cost is reduced, and environmental protection is facilitated; dangerous chemical products are not used, so that the safety is high; excessive methanol in the reaction can be recycled, so that the preparation cost of trimethyl phosphate is further reduced; and the purity of the prepared trimethyl phosphate is greater than or equal to 99.5%, and the yield is greater than or equal to 90%.

The invention relates to a fixed-bed pure-oxygen continuous gasification device and process adaptable to diversified coals. According to the device and the process, CO2, pure oxygen and superheated steam serve as gasifying agents and subject to a gasification reaction with feed coal in a fixed-bed pure-oxygen continuous gasifier, so as to generate gasified coal gas; the gasified coal gas enters a dust remover so as to remove solid particles from the gasified coal gas, and a water cooler is arranged at the upper part of the efficient dust remover and is used for recovering part of sensible heat from the gasified coal gas; the gasified coal gas subjected to dust removal enters a heat-pipe heat exchanger for heat recovery, and low-pressure steam is a byproduct; and low-temperature gasified coal gas enters a low-pressure coal gas scrubbing tower for final cooling and dust removal, and scrubbed water gas is connected and conveyed to a gas tank. The content of CO and H2 in the gasified coal gas can reach 80% or more, the ratio range of adjustment of CO among ingredients of the coal gas is 40-65%, the ratio range of adjustment of H2 among the ingredients of the coal gas is 5-40%, and the gasified coal gas can serve as raw material gas of a variety of chemical products through being subjected to further deep treatment by processes such as conversion and purification.
