来クロロホルムを殺菌、殺虫剤として用いることは行わ
れていない。[Effect] Chloroform has extremely strong bactericidal and insecticidal properties. However, chloroform gradually decomposes due to sunlight and oxygen in the air and produces phosgene, which is extremely toxic and dangerous to the human body, so using chloroform alone as a disinfectant or insecticide poses a major safety problem. Therefore, chloroform has not been conventionally used as a disinfectant or insecticide.
一方エチルアルコールまたは消毒用アルコールは、殺菌
性及び殺虫性を有するが、その殺菌効果及び殺虫効果は
比較的弱く、エチルアルコールまたは消毒用アルコール
の単体では害虫等の駆除効果を余り期待することができ
ない。On the other hand, ethyl alcohol or disinfecting alcohol has bactericidal and insecticidal properties, but its bactericidal and insecticidal effects are relatively weak, and ethyl alcohol or disinfecting alcohol alone cannot be expected to be very effective in exterminating pests. .

無くすことができ、安全性を確保した上で、クロロホル
ムの強力な殺菌、殺虫性能を活用することができる。In addition, ethyl alcohol acts as a stabilizer for chloroform and suppresses the production of phosgene, so if you mix a large amount of ethyl alcohol or rubbing alcohol with chloroform as described above, you can eliminate the production of phosgene. This makes it possible to utilize the powerful sterilizing and insecticidal properties of chloroform while ensuring safety.
更に、アルコールは適当な濃度であれば飲用できるほど
人体に無害であり、クロロホルムは揮発性で、揮発後の
残留がほとんどないため、被処理物に薬剤が残留するこ
とによる薬害の発生を無くすことができる。Furthermore, alcohol is harmless enough to the human body to be drinkable at an appropriate concentration, and chloroform is volatile and leaves almost no residue after volatilization, so it eliminates the occurrence of chemical damage caused by chemicals remaining in the treated material. I can do it.

℃以上に設定すると顕著な殺菌、殺虫効果が得られるこ
とが確認された。When the object to be treated was stored in a sealed container and sterilization and insecticide gas with a lower limit of chloroform content of 10% by volume or more was injected into the container up to saturated vapor pressure, a large insecticidal effect was obtained. Obtained. In this case, the temperature inside the container is set to 20
It was confirmed that remarkable bactericidal and insecticidal effects can be obtained when the temperature is set above ℃.
消毒用アルコールの代りにエチルアルコールを用いた場
合に顕著な殺虫効果を得るためには、クロロホルムの含
有率を２０容量％以上にすることが必要であった。In order to obtain a significant insecticidal effect when ethyl alcohol is used instead of disinfecting alcohol, it is necessary to increase the chloroform content to 20% by volume or more.
さらに、容器内を減圧した後に、上記殺菌、殺虫剤のガ

てそれぞれの殺虫効果を確認する実験を行った。[Experiment Example - Experiment 1 First, each of 99.5% ethyl alcohol, disinfecting alcohol containing 22% water, and chloroform (usually commercially available as chloroform) containing 1% ethyl alcohol as a stabilizer was added. Experiments were conducted to confirm the insecticidal effects of each using each as a sample.

で行った。In the experiment, as shown in Fig. 1, a large number of wide-mouth cylindrical glass containers 2 whose top openings are closed with lids 1 are prepared, and 20 black crickets (10 days to 2 weeks old) as specimens 3 are placed in each container 2. I put one in. Then, 0.2 cc L of each sample was added to the absorbent cotton 4 filled in the recess provided in the lid 1 of each container.
The container 2 is filled with gas by infiltration and evaporation, and every time a predetermined time elapses, all the samples in the predetermined container are transferred to another container, and the samples are filled with the gas of each sample. The relationship between the contact time and the survival rate of the specimen 24 hours after the gas contact was determined. Experiments were conducted at room temperature of 25°C.
その結果は第２図に示す通りであり、同図においてａ、
ｂ及びＣはそれぞれ９９．５％エチルアルコール、水を
２２％含む消毒用アルコール、及び９９％クロロホルム
の場合を示している。The results are shown in Figure 2, where a,
b and C show the cases of 99.5% ethyl alcohol, disinfecting alcohol containing 22% water, and 99% chloroform, respectively.
この結果から明らかなように、９９．５％エチルアルコ

００％の死亡率が得られないが、クロロホルムの場合に
はわずか２分接触させるだけで９０％の死亡率が得られ
、３分接触させれば１００％の死亡率が得られる。As is clear from these results, when 99.5% ethyl alcohol and disinfecting alcohol are used alone, the specimen must be exposed to each gas for 20 minutes to
However, in the case of chloroform, a 90% mortality rate can be obtained with just 2 minutes of contact, and a 100% mortality rate can be obtained with 3 minutes of contact.

Samples with various [%] were prepared, and the relationship between the contact time of the specimen and the sample gas and the survival rate after 24 hours was determined in the same manner as above. Figure 3 shows the results.
In the figure, a to g each represent the chloroform content α (volume %) of 15%.
２０％、２２％、２５％、 ３０％、４０％及び５０％
とした場合である。20%, 22%, 25%, 30%, 40% and 50%
This is the case.

ことが確認された。This experiment revealed that if the chloroform content is 30% or more, 100% mortality can be achieved by simply exposing the specimen to the gas for 3 minutes. That is, it was confirmed that when the content of chloroform is 30% or more, a strong insecticidal effect similar to that obtained when chloroform is used alone can be obtained.
またクロロホルムの含有率を３０％未満とした場合でも
、消毒用アルコールを単独で用いる場合のガス接触時間
（２０分）よりも短い時間（１５％の場合で８分）で１
００％の死亡率を得ることができた。Furthermore, even when the chloroform content is less than 30%, the gas contact time (8 minutes in the case of 15%) is shorter than the gas contact time (20 minutes) when using rubbing alcohol alone.
A mortality rate of 0.00% was achieved.
尚消毒用アルコールとクロロホルムとを混合させた場合
のクロロホルムの飽和濃度は２５°Ｃで約４５％であり
、これ以上のクロロホルムを加えると懸濁状態になる。Note that when rubbing alcohol and chloroform are mixed, the saturation concentration of chloroform is approximately 45% at 25°C, and if more chloroform is added, the mixture becomes suspended.
したがってクロロホルムの含有率はその温度の飽和濃度
以下に設定するのが良い。Therefore, the content of chloroform is preferably set below the saturation concentration at that temperature.

３５％、４０％、４５％及び５０％とした場合である。Experiment 3 In this experiment, the insecticidal effect of mixing 99.5% ethyl alcohol with chloroform was investigated. The experimental method was the same as Experiment 1, and the content of chloroform (% by volume)
The relationship between the contact time between the specimen and the sample gas and the survival rate after 24 hours was determined by varying the parameters. Figure 4 shows the results. In the figure, a to h represent the chloroform content α, respectively: 10%, 20%, 25%, 30%,
This is the case of 35%, 40%, 45% and 50%.
尚同図においてクロロホルムの含有率が１０容量％の場

強力な殺虫効果が得られることが明らかになった。From this experiment, even when using a mixture of ethyl alcohol and chloroform that does not contain substantially water, a stronger insecticidal effect can be obtained than when using rubbing alcohol alone, and especially when the chloroform content is 20% by volume or more. If you do so, you can get a noticeable effect. It has also been revealed that when the content of chloroform is 45% by volume, a strong insecticidal effect equivalent to that of chloroform alone can be obtained.
