Crystalline calcium formate maka akpụkpọ anụ akpụkpọ anụ

Usoro mmepụta:

1. Usoro nnọpụiche

Formic acid na-anọpụ iche na lime hydrated iji mepụta calcium formate, a na-enwetakwa usoro calcium azụmahịa site na nchacha.

2. Usoro ndakpọ ngwakọta

Na ọnụnọ nke ihe na-akpata, sodium formate na calcium nitrate na-enweta mmeghachi omume nbibi okpukpu abụọ iji nweta usoro calcium na-emepụta sodium nitrate. Azụmahịa calcium formate nwetara site na nnụcha.

3. Usoro nke ngwaahịa nke epoxy fatty acid methyl ester

Mmepụta nke epoxy fatty acid methyl ester na-etolite ngwa ngwa, a na-emepụta nnukwu formic acid site na ngwaahịa na usoro mmepụta. Otu n'ime atụmatụ ojiji nke formic acid sitere na ngwaahịa a bụ imepụta calcium formate.

4. Usoro ọmụmụ

Na usoro mmepụta, a na-eji calcium hydroxide na-enye ọnọdụ mmeghachi omume bụ isi, a na-agbakwunye formic acid na mmeghachi omume na-esote na calcium hydroxide neutralization usoro n'otu oge iji mepụta calcium formate.

Formic acid bụ carboxylic acid nwere ike itinye na olefins.Formic acid n'omume acid (dị ka sulfuric acid, hydrofluoric acid), na olefins na-eme ngwa ngwa na-emepụta usoro. Otú ọ dị, mmeghachi omume dị n'akụkụ yiri mmeghachi omume Koch nwekwara ike ime, na ngwaahịa ahụ bụ nnukwu carboxylic acid.
