Ọrọ Iṣaaju

methyl hydrogen azelate, tun mọ bi polycarboxylate, jẹ pataki polima molikula pataki. O ni awọn ohun-ini wọnyi:

 

1. Awọn ohun-ini ti ara: methyl hydrogen azelate jẹ awọ ti ko ni awọ tabi omi-ofeefee ina, pẹlu solubility ti o dara, ti o ni omi, oti ati awọn ohun elo ti o wa ni erupẹ.

 

2. Awọn ohun-ini kemikali: methyl hydrogen azelate jẹ ẹya ester pẹlu iduroṣinṣin to gaju ati resistance kemikali. O le jẹ hydrolyzed si azelaic acid ati kẹmika.

 

Awọn lilo akọkọ ti methyl hydrogen azelate pẹlu:

 

1. Polymer igbaradi: methyl hydrogen azelate le jẹ polymerized pẹlu awọn monomers miiran lati ṣeto awọn polima molikula giga. Awọn polima wọnyi ni awọn ohun-ini to dara julọ ati pe o le ṣee lo ni ọpọlọpọ awọn ile-iṣẹ bii awọn aṣọ, awọn lẹ pọ, awọn pilasitik, awọn okun, ati bẹbẹ lọ.

 

2. Surfactant: methyl hydrogen azelate le ṣee lo bi emulsifier, dispersant and wetting agent, lilo pupọ ni awọn ohun ikunra, awọn ohun elo ati awọn ọja itọju ti ara ẹni ati awọn aaye miiran.

 

Awọn ọna fun igbaradi methyl hydrogen azelate jẹ nipataki bi atẹle:

 

1. Iṣeduro transesterification: ifasilẹ transesterification ni a ṣe pẹlu ọti ti kii ṣe ati methyl formate ni iwaju ayase acid lati gba methyl hydrogen azelate.

 

2. Idahun esterification taara: esterification ti nonanol ati formate labẹ iṣẹ ti ayase acid lati ṣe ina methyl hydrogen azelate.

 

Ṣe akiyesi alaye aabo atẹle nigba lilo ati mimu methyl hydrogen azelate:

 

1. methyl hydrogen azelate jẹ irritating ati pe o yẹ ki o fi omi ṣan lẹsẹkẹsẹ nigbati o ba ni ifọwọkan pẹlu awọ ara ati oju.

 

2. Yẹra fun simi simi ti methyl hydrogen azelate ati lo ni aaye ti o ni afẹfẹ daradara.

 

3. methyl hydrogen azelate ni majele kekere, ṣugbọn igba pipẹ ati ifihan ti o tobi le ni ipa lori ilera, ati pe o yẹ ki o yẹra fun ifihan ti o pọju.

 

4. Nigbati o ba tọju ati gbigbe methyl hydrogen azelate, pa a mọ kuro ninu ina ati iwọn otutu giga lati ṣe idiwọ ewu ti ijona ati bugbamu.

 

Jọwọ ṣe akiyesi pe ṣaaju lilo methyl hydrogen azelate tabi eyikeyi kemikali, o yẹ ki o farabalẹ ka ati tẹle awọn ilana aabo ti o yẹ.
