What is SEC-Butylamine?
Sec-butylamine, also known as “2-aminobutane”, has a chiral carbon atom in the molecule, so it has a pair of optically active enantiomers and an optically inactive anti-racemate. It is miscible with water and ethanol, has stimulating effect on mucous membrane and skin, LD50380mg/kg (orally in mice).
Sec-butylamine is a protective fungicide that has antibacterial activity against a variety of molds. In 1962, after Dr. Eck discovered its bactericidal effect, it was widely used in the storage period of citrus, apples, pears, peaches and bananas. In 1975, the United Nations Food and Agriculture Organization and the World Health Organization evaluated and recommended sec-butylamine for the first time, and now it has been widely used in many countries such as the United States, Britain, and Australia. Post-harvest processing.
- Sec-butylamine is widely used and can be used as a preservative, a fruit washing agent, and a fumigant. It can be used for fresh-keeping of fruits, garlic sprouts and green peppers, and can be used in moderation according to production needs.
- Intermediates for the production of pesticides, pharmaceuticals and siloxanes, auxiliaries for polymerization and rubber additives.
In terms of citrus, Dr. Eckert of the United States discovered in 1962 that volatile fatty amines have inhibitory effects on citrus green and green mold. In 1975, the Food and Agriculture Organization of the United Nations and the World Health Organization jointly proposed the residues of sec-butylamine on citrus: dried citrus pulp and molasses 50mg/kg, citrus pulp 30mg/kg, citrus juice 0.5mg/kg , China GB2760-86 stipulates that the residue of sec-butylamine in citrus pulp is 0.005g per kg.
Hebei Agricultural University soaked citrus fruits with sec-butylamine aqueous solution. After 70 days of storage, the good fruit rate was 93.78%, which was 23.58% higher than that of the control group. After the later scientific research and experiments, the series of sec-butylamine preservatives have been successively developed, namely AB preservatives, No. 2 citrus preservatives, 2-AB carbonate salts, citrus rotjing and tangerine preservatives. By adjusting the proportion of each component in the series of preservatives, various citrus fruits can obtain good storage effect under different harvest periods of early, middle and late.
In terms of apples, sec-butylamine has the effects of inhibiting, contacting, fumigating and infiltrating spores and mycelium of apple ringworm. Using sec-butylamine diluent to soak the fruit for 1 min, air-dry it in the cellar, the control effect of Chiyang, Jinguan, Marshal and Ganlu varieties can reach 88.5% to 98.6%. Due to the low vapor pressure of sec-butylamine, fumigation can also be used. When packaging in plastic bags, place a penicillin bottle in every 20kg fruit bag, containing 4-5g of sec-butylamine powder, seal it with gauze, and slowly release the gas , the control rate can reach more than 90%. In terms of longan, fumigation and fruit dipping were used to treat longan fruits. After one month of storage, the average good fruit rate of fumigation method was 99.05%, and the good fruit rate of dipping method was 97.3%, while the untreated longan control group was only 99.05%. 39.6%, excellent anti-corrosion effect.
