Acide-base itabogamye ya acide ya acetike mu gukaraba no gusiga amarangi no kwita kubikoresha

intro

Izina ryimiti ya acide acetike ni acide acike, formula ya chimique CH3COOH, kandi ibirimo aside aside irike 99% byashyizwe mubibarafu munsi ya 16 ° C, bizwi kandi nka acide glacial acetic.Acide acikeni ibara, amazi-ashonga, arashobora kubangikanywa namazi murwego urwo arirwo rwose, ruhindagurika, ni acide organique idakomeye.

Nka acide kama, aside ya asike ntabwo ikoreshwa cyane muri synthesis organique, inganda zikora imiti, ibiryo, ubuvuzi nizindi nganda, ahubwo ikoreshwa no muruganda rwo gukaraba no gusiga amarangi.

Gukoresha aside acike mu gukaraba no gusiga amarangi

01 Acide yo gushonga imikorere ya acide ya acetike mugukuraho ikizinga

Acide acikenka vinegere kama, irashobora gushonga aside tannic, aside yimbuto nibindi biranga aside irike, irangi ryatsi, umutobe w umutobe (nku icyuya cyimbuto, umutobe wimbuto, umutobe winyanya, umutobe wibinyobwa bidasembuye, nibindi), imiti yubuvuzi, amavuta ya chili na andi mabara, ayo marangi arimo ibintu bya vinegere kama, acide acetike nkikuraho ikizinga, birashobora gukuraho ibintu bya acide kama ngengabihe, nkuko byerekeranye nibintu bya pigment biri murirangi, Hanyuma hamwe nubuvuzi bwa okiside, byose birashobora kuvaho.

Acide-base itabogamye ya acide munganda zo gukaraba no gusiga irangi

Acide acikeubwayo ni acide nkeya kandi irashobora kutabangikanywa nifatizo.

.

(2) Kutabogama kwa acide acike na alkali birashobora kandi kugarura ibara ryimyenda iterwa ningaruka za alkali.

. yumuti wo guhumeka hamwe na acide acetike irashobora kwihutisha inzira yo guhumeka.

.

. kubera icyuma aurora phenomenon.

Ku marangi ashonga amazi arimo hydroxyl na acide sulfonique, imyenda ya fibre irwanya alkali mbi (nka silk, rayon, ubwoya), bitewe na vinegere, ifasha amabara no gutunganya amabara ya fibre.

Kubwibyo, imyenda imwe nimwe idahwitse ya alkaline kandi igahita igabanuka mugikorwa cyo gukaraba irashobora kongerwamo aside acike ya acetike mumyenda yo kumesa kugirango ikosore ibara ryimyenda.

Duhereye kuri iyi ngingo,acideikoreshwa cyane mu nganda zo gukaraba no gusiga amarangi, ariko muburyo bwo gusaba nayo igomba kwitondera ibibazo bikurikira.

Ku mwenda urimo fibre acide ya acetike, mugihe ukoresheje acide acetike kugirango ukureho ikizinga, ugomba kwitonda cyane kugirango witondere kwibanda kuri acide acike ntabwo iri hejuru cyane. Ibi biterwa nuko fibre acetate ikozwe mubiti, ubwoya bw'ipamba nibindi bikoresho bya selile na acide acetike na acetate, kutarwanya vinegere, aside ikomeye irashobora gutesha fibre acetate. Iyo ikizinga gishyizwe kuri fibre acetate nigitambara kirimo fibre acetate, hagomba kuvugwa ingingo ebyiri:

(1) Gukoresha neza acide acike ni 28%.

.

Icyitonderwa cyo gukoresha aside irike niyi ikurikira:

(1) Irinde guhura n'amaso, niba uhuye cyane na acide fermented, uhite woza amazi.

(2) Guhura nibikoresho byicyuma bigomba kwirindwa kubyara ruswa.

(3) Imikoreshereze yibiyobyabwenge no guhuza ibiyobyabwenge bya alkaline birashobora kubaho kutabogama no gutsindwa.
