Description
Technical field
The present invention relates to a kind of formulation of insecticide, soil fumigant, concrete for to contain 1.3---a kind of formulation of dichloropropylene and chloropicrin.
Technical background
1.3--dichloropropylene, English name: 1.3--1,3-dichloropropene; 1,3-dichloropropylene, international numbering: 33528 CAS:542-75-6, another name: 1.3---D or 3---Chloroallyl chlorine, molecular formula: C3H4Cl2; ClCH=CHCH2Cl.Molecular weight: 111.00, fusing point-84 ℃, boiling point: 112 ℃ (cis), 104 ℃ (trans), relative density 1.2170 (suitable), 1.2240 (instead), gas density 3.8g/L (20 ℃).Be colourless volatile liquid, the smell like chloroform is arranged.Risk markings: 7 (flammable liquids), agricultural is used as soil fumigant, preservative, mixes with dichloropropane and makes soil fumigant.Fungi and soil insect there is certain control efficiency.
Chloropicrin, chemical name are trichloronitromethane, and international name: chloropicrin, its mp-64 ℃, bp112.4 ℃, d204 1.656, and is water-soluble hardly, is dissolved in ether, acetone and other organic solvent.Since 1908 as insecticide (BP2387). because chloropicrin is volatile, chemical property is stable, and noresidue is used for always for many years that grain is stifling, the soil-fumigating desinsection, and soil disinfection, stiflingly kill mouse, aspects such as timber and medicinal material fumigant insect killing.
Above-mentioned two kinds of chemicals, there are many problems in agriculture application practice proof.As 1.3---dichloropropylene, ground temperature are lower than 15 ℃, and the processing time needed more than three weeks, and weather is than cold district mostly, easily farming season and can't using by mistake.In addition because of underground water is had pollution, in U.S.'s legal provisions 1.3---dichloropropylene need have certain buffer zone with the population residence, adopts the chemigation method to need the 30.5m buffer strip; And adopt the injection buffer strip is 91.5m.And only better to the nematode effect, general to the fungi effect.Chloropicrin is used for soil-fumigating, and action need band breathing mask and special syringe also need overlay film after the dispenser, needs certain sealing BHT, and very loaded down with trivial details, control efficiency is better to fungi, and anti-nematode is general.So have chloropicrin liquid and 1.3 on the market---dichloropropylene liquid mix formulation.As Telonec-17 (if 78.3%1.3--dichloropropylene+16.5 chlorinations) and Telonec-35 commodity sellings such as (61.8%1.3---dichloropropylenes+35 chloropicrins).Such intermixture, although but expanding prevention spectrum after mixing, owing to be volatile liquid all, dosage is very big.---1.3 dichloropropylene (92%) content mu formulation rate needs 18---24kg, chloropicrin (98%) content mu formulation rate needs 30kg, and utilization ratio of drug is extremely low.The toxic gas that can't decompose enters atmosphere when loosing gas in a large number, not only wastes medicine and strengthens the dispenser expense, and caused severe contamination to environment.Therefore, chloropicrin and 1.3---the former medicine of dichloropropylene uses not only dangerous but also uneconomical.
Summary of the invention
Shortcoming at above-mentioned existing product exists the purpose of this invention is to provide a kind of chloropicrin and 1.3---the mixing formulation of dichloropropylene, improve its safety in utilization, improve utilization ratio of drug simultaneously, with its reach drug effect better, wider purpose.
Basic point of the present invention is to make chloropicrin and 1.3---the former medicine of dichloropropylene is adsorbed on a kind of nonhazardous, the pollution-free solid absorbent, and the slow release medicine of energy prolonged drug effect when this solid dosage forms was used, and its concrete technical scheme is;
1, adsorbent is adsorbed preceding activation, then dry, seal stand-by.
2, will fill chloropicrin and 1.3---the mixed vapour of the certain ratio of dichloropropylene feeds in the above-mentioned adsorbent, reach requirement to the adsorbent increment till.
The adsorbent that 3, will adsorb mist makes its quality even through mixing, packaging closures.
Wherein, adsorbent is that one or both mixtures such as active carbon, atlapulgite, activated alumina, polymeric adsorbent are formed, have after the activation certain adsorbing capacity all can, be best with the active carbon, especially with 0.1---1.0mm is the most suitable.Can use equipment in addition during the adsorbent activation,, also can in adsorption tanks, activate, use just can do absorption after the drying as activation pot or post activation.Can carry out at normal temperatures and pressures during absorption, but adsorption rate is slow, if adsorption tanks negative pressure slightly, during the mixed liquor constant-temperature evaporation, adsorption rate can be hurry up; The evaporation if mixed liquor is heated, then adsorption rate can be faster.The mode of adsorbing heating evaporation with normal temperature and pressure down is more suitable.Absorption is wanted coadaptation mutually with evaporation, should accelerate adsorption rate, and non-vaporising adsorb too soon and makes the mist effusion again, thus when evaporating temperature with 70 ℃---boiling point is advisable.This 1.3---the hybrid solid formulation of dichloropropylene and chloropicrin is with the different different contents that form of both proportionings, and 1: 2 to 5: otherwise 5 or, total content is with 20---30% for well.Product is basic packing with the plastic bottle, opens bottle cap during use and takes, and little pungent is only arranged, and need not breathing mask.Product is imbedded soil layer 15 in actual use---and after the 20cm, available gas ground temperature is beginning release more than 10 ℃, and temperature rise is accelerated gradually everywhere later on, and last desorption is closely zero.Equally with former drug effect fruit kill soil insect and germ, its control is composed wider, and residual effect can reach more than 6 months.Utilization ratio of drug greatly improves, safety, economy, the effect that plays cover crop that can be more effective, more lasting.
Compare with existing product, the characteristics that the present invention had are;
1, product is a solid dosage forms, uses the safety of storing up with fortune that outstanding the raising arranged.Under in order to be effective prerequisite, easy to use, purposes wide, few with former dose, cost reduces significantly, drug slow discharges and the drug effect phase is long, is unique so far 1.3---the hybrid solid formulation of dichloropropylene and chloropicrin.
2, make this formulation with absorption method, show an interesting new approach, technology is reasonable, and method is easy, and three-waste free discharge, and environment is not had any impact.
